inode_nohighmem() is sufficient to make sure that page_get_link() won't try to allocate a highmem page. Moreover, it is sufficient to make sure that page_symlink/__page_symlink won't do the same thing. However, any filesystem that manually preseeds the symlink's page cache upon symlink(2) needs to make sure that the page it inserts there won't be a highmem one. Fortunately, only nfs and shmem have run afoul of that... Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

Last window's set was short, but I warned that this one would be bigger, and so it is. We've got 19 patches: - A patch from Abhi Das to propagate the GFS2_DIF_SYSTEM bit so that newly added journals don't get flagged, deleted, and recreated by fsck.gfs2. - Two patches from Andreas Gruenbacher to improve GFS2 performance where extended attributes are involved. - A patch from Andy Price to fix a suspicious rcu dereference error. - Two patches from Ben Marzinski that rework how GFS2's NFS cookies are managed. This fixes readdir problems with nfs-over-gfs2. - A patch from Ben Marzinski that fixes a race in unmounting GFS2. - A set of four patches from me to move the resource group reservations inside the gfs2 inode to improve performance and fix a bug whereby get_write_access improperly prevented some operations like chown. - A patch from me to spinlock-protect the setting of system statfs file data. This was causing small discrepancies between df and du. - A patch from me to reintroduce a timeout while clearing glocks which was accidentally dropped some time ago. - A patch from me to wait for iopen glock dequeues in order to improve deleting of files that were unlinked from a different cluster node. - A patch from me to ensure metadata address spaces get truncated when an inode is evicted. - A patch from me to fix a bug in which a memory leak could occur in some error cases when inodes were trying to be created. - A patch to consistently use iopen glocks to transition from the unlinked state to the deleted state. - A patch to fix a glock reference count error when inode creation fails. - A patch from Junxiao Bi to fix an flock panic. - A patch from Markus Elfring that removes an unnecessary if" * tag 'gfs2-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: gfs2: fix flock panic issue GFS2: Don't do glock put on when inode creation fails GFS2: Always use iopen glock for gl_deletes GFS2: Release iopen glock in gfs2_create_inode error cases GFS2: Truncate address space mapping when deleting an inode GFS2: Wait for iopen glock dequeues gfs2: clear journal live bit in gfs2_log_flush gfs2: change gfs2 readdir cookie gfs2: keep offset when splitting dir leaf blocks GFS2: Reintroduce a timeout in function gfs2_gl_hash_clear GFS2: Update master statfs buffer with sd_statfs_spin locked GFS2: Reduce size of incore inode GFS2: Make rgrp reservations part of the gfs2_inode structure GFS2: Extract quota data from reservations structure (revert 5407e242) gfs2: Extended attribute readahead optimization gfs2: Extended attribute readahead GFS2: Use rht_for_each_entry_rcu in glock_hash_walk GFS2: Delete an unnecessary check before the function call "iput" gfs2: Automatically set GFS2_DIF_SYSTEM flag on system files

Pull misc vfs updates from Al Viro: "All kinds of stuff. That probably should've been 5 or 6 separate branches, but by the time I'd realized how large and mixed that bag had become it had been too close to -final to play with rebasing. Some fs/namei.c cleanups there, memdup_user_nul() introduction and switching open-coded instances, burying long-dead code, whack-a-mole of various kinds, several new helpers for ->llseek(), assorted cleanups and fixes from various people, etc. One piece probably deserves special mention - Neil's lookup_one_len_unlocked(). Similar to lookup_one_len(), but gets called without ->i_mutex and tries to avoid ever taking it. That, of course, means that it's not useful for any directory modifications, but things like getting inode attributes in nfds readdirplus are fine with that. I really should've asked for moratorium on lookup-related changes this cycle, but since I hadn't done that early enough... I *am* asking for that for the coming cycle, though - I'm going to try and get conversion of i_mutex to rwsem with ->lookup() done under lock taken shared. There will be a patch closer to the end of the window, along the lines of the one Linus had posted last May - mechanical conversion of ->i_mutex accesses to inode_lock()/inode_unlock()/inode_trylock()/ inode_is_locked()/inode_lock_nested().

Breakage due to conflicting development is possible, in which case this pull will have to be reverted - however, these changes have been in linux-next since Dec 7th without any problems reported.

Pull LED subsystem updates from Jacek Anaszewski: "Besides regular driver updates, we introduce a portion of LED core improvements, that allow to avoid the need for using work queues in the LED class drivers, that set brightness in a blocking way. Affected LED class drivers are being optimized accordingly. - LED core improvements: - use EXPORT_SYMBOL_GPL consistently, - add two new LED_BLINK_ flags, - rename brightness_set_sync op to brightness_set_blocking, - add led_set_brightness_nosleep{nopm} functions, - use set_brightness_work for the blocking op, - drivers shouldn't enforce SYNC/ASYNC brightness setting, - turn off the LED and wait for completion on unregistering LED class device, - add managed version of led_trigger_register, - add description of brightness setting API to the LED class doc. - Remove work queues from drivers: leds-tlc591xx, leds-88pm860x, leds-adp5520, leds-bd2802, leds-blinkm, leds-lm3533, leds-lm3642, leds-pca9532, leds-lp3944, leds-lp55xx, leds-lp8788, leds-lp8860, leds-pca955x, leds-pca963x, leds-wm831x, leds-da903x, leds-da9052, leds-dac124d085, leds-lt3593, leds-max8997, leds-mc13783, leds-regulator, leds-wm8350, leds-max77693, leds-aat1290, leds-ktd2692, leds-gpio, leds-pwm, leds-lm355x, leds-ns2. - Replace brightness_set op with a new brightness_set_blocking op to make the drivers compatible with led triggers: leds-ipaq-micro, leds-powernv. - Add missing of_node_put: leds-ktd2692, leds-aat1290, leds-max77693. - Make the driver explicitly non-modular: ledtrig-cpu, ledtrig-ide-disk, leds-syscon. - Improvements to leds-bcm6328: - reuse bcm6328_led_set() instead of copying its functionality, - swap LED ON and OFF definitions, - improve blink support, - simplify duplicated unlock in bcm6328_blink_set, - add little endian support, - remove unneded lock when checking initial LED status, - add HAS_IOMEM dependency, - code cleaning. - Improvements to leds-bcm6358: - use bcm6358_led_set() in order to get rid of the lock, - merge bcm6358_led_mode and bcm6358_led_set, - add little endian support, - remove unneded lock when checking initial LED status, - add HAS_IOMEM dependency, - remove unneeded busy status check. - Call led_pwm_set() in leds-pwm to enforce default LED_OFF. - Fix duration to be msec instead of jiffies: ledtrig-transient. - Removing NULL check: leds-powernv. - Use platform_register/unregister_drivers(): leds-sunfire. - Fix module license specification: ledtrig-oneshot. - Fix driver description and make license match the header: leds-pwm. - Remove checking for state < 1 in flash_strobe_store(): led-class-flash. - Use led_set_brightness_sync for torch brightness: v4l2-flash-led-class" * tag 'leds-for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds: (68 commits) leds: add HAS_IOMEM dependency to LEDS_BCM6328/LEDS_BCM6358 leds: core: add managed version of led_trigger_register leds: bcm6358: remove unneeded busy status check leds: bcm6328: improve blink support leds: bcm6358: merge bcm6358_led_mode and bcm6358_led_set leds: bcm6328: simplify duplicated unlock in bcm6328_blink_set leds: bcm6358: add little endian support leds: bcm6328: add little endian support leds: bcm6358: remove unneded lock when checking initial LED status leds: bcm6358: Use bcm6358_led_set() in order to get rid of the lock leds: bcm6328: remove unneded lock when checking initial LED leds: bcm6328: code cleaning leds: syscon: Make the driver explicitly non-modular leds: ledtrig-ide-disk: Make the driver explicitly non-modular leds: ledtrig-cpu: Make the driver explicitly non-modular leds: sunfire: Use platform_register/unregister_drivers() leds: max77693: Add missing of_node_put leds: aat1290: Add missing of_node_put leds: powernv: Implement brightness_set_blocking op leds: ipaq-micro: Implement brightness_set_blocking op ...

Pull pin control updates from Linus Walleij: "This is the bulk of pin control patches for the v4.5 series. Notably I have a patch to driver core from Stephen Boyd in the pull request, this has been ACKed by Greg so it should be OK. The internal API needed some tweaking to allow modular Qualcomm pin controllers. There is a bit of development history in here but it should all add up nicely and has boiled in linux-next. For example I merged in v4.4-rc5 to get rid of some nasty merge conflicts. Summary: - New drivers: - PXA2xx pin controller support - Broadcom NSP pin controller support - New subdrivers: - Samsung EXYNOS5410 support - Qualcomm MSM8996 support - Qualcomm PM8994 support - Qualcomm PM8994 MPP support - Allwinner sunxi H3 support - Allwinner sunxi A80 support - Rockchip RK3228 support - Rename the Cygnus pinctrl driver to "iproc" as it is more generic than was originally thought. - A bunch of Lantiq/Xway updates especially from the OpenWRT people. - Several refactorings for the Super-H SH PFC pin controllers.
