If user specifies too low end sector for trimming, f2fs_trim_fs() will use uninitialized value as a number of trimmed blocks and returns it to userspace. Initialize number of trimmed blocks early to avoid the problem.

Previously, init_inode_metadata does not hold any parent directory's inode page. So, f2fs_init_acl can grab its parent inode page without any problem. But, when we use inline_dentry, that page is grabbed during f2fs_add_link, so that we can fall into deadlock condition like below. INFO: task mknod:11006 blocked for more than 120 seconds. Tainted: G OE 3.17.0-rc1+ #13 "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. mknod D ffff88003fc94580 0 11006 11004 0x00000000 ffff880007717b10 0000000000000002 ffff88003c323220 ffff880007717fd8 0000000000014580 0000000000014580 ffff88003daecb30 ffff88003c323220 ffff88003fc94e80 ffff88003ffbb4e8 ffff880007717ba0 0000000000000002 Call Trace: [<ffffffff8173dc40>] ? bit_wait+0x50/0x50 [<ffffffff8173d4cd>] io_schedule+0x9d/0x130 [<ffffffff8173dc6c>] bit_wait_io+0x2c/0x50 [<ffffffff8173da3b>] __wait_on_bit_lock+0x4b/0xb0 [<ffffffff811640a7>] __lock_page+0x67/0x70 [<ffffffff810acf50>] ? autoremove_wake_function+0x40/0x40 [<ffffffff811652cc>] pagecache_get_page+0x14c/0x1e0 [<ffffffffa029afa9>] get_node_page+0x59/0x130 [f2fs] [<ffffffffa02a63ad>] read_all_xattrs+0x24d/0x430 [f2fs] [<ffffffffa02a6ca2>] f2fs_getxattr+0x52/0xe0 [f2fs] [<ffffffffa02a7481>] f2fs_get_acl+0x41/0x2d0 [f2fs] [<ffffffff8122d847>] get_acl+0x47/0x70 [<ffffffff8122db5a>] posix_acl_create+0x5a/0x150 [<ffffffffa02a7759>] f2fs_init_acl+0x29/0xcb [f2fs] [<ffffffffa0286a8d>] init_inode_metadata+0x5d/0x340 [f2fs] [<ffffffffa029253a>] f2fs_add_inline_entry+0x12a/0x2e0 [f2fs] [<ffffffffa0286ea5>] __f2fs_add_link+0x45/0x4a0 [f2fs] [<ffffffffa028b5b6>] ? f2fs_new_inode+0x146/0x220 [f2fs] [<ffffffffa028b816>] f2fs_mknod+0x86/0xf0 [f2fs] [<ffffffff811e3ec1>] vfs_mknod+0xe1/0x160 [<ffffffff811e4b26>] SyS_mknod+0x1f6/0x200 [<ffffffff81741d7f>] tracesys+0xe1/0xe6 Signed-off-by: NJaegeuk Kim <jaegeuk@kernel.org>

Pull ARM SoC fixes from Olof Johansson: "A surprisingly small batch of fixes for -rc3. Suspiciously small, I'd say. Anyway, most of this are a few defconfig updates. Some for omap to deal with kernel binary size (moving ipv6 to module, etc). A larger one for socfpga that refreshes with some churn, but also turns on a few options that makes the newly-added board in my bootfarm usable for testing. OMAP3 will also now warn when booted with legacy (non-DT) boot protocols, hopefully encouraging those who still care about some of those platforms to submit DT support and report bugs where needed. Nothing stops working though, this is just to warn for future deprecation. Beyond this, very few actual bugfixes.

Pull MTD fixes from Brian Norris: "Three main MTD fixes for 3.18: - A regression from 3.16 which was noticed in 3.17. With the restructuring of the m25p80.c driver and the SPI NOR library framework, we omitted proper listing of the SPI device IDs. This means m25p80.c wouldn't auto-load (modprobe) properly when built as a module. For now, we duplicate the device IDs into both modules. - The OMAP / ELM modules were depending on an implicit link ordering. Use deferred probing so that the new link order (in 3.18-rc) can still allow for successful probing. - Fix suspend/resume support for LH28F640BF NOR flash" * tag 'for-linus-20141102' of git://git.infradead.org/linux-mtd: mtd: cfi_cmdset_0001.c: fix resume for LH28F640BF chips mtd: omap: fix mtd devices not showing up mtd: m25p80,spi-nor: Fix module aliases for m25p80 mtd: spi-nor: make spi_nor_scan() take a chip type name, not spi_device_id mtd: m25p80: get rid of spi_get_device_id

Merge tag 'fixes-against-v3.18-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes Merge "omap fixes against v3.18-rc2" from Tony Lindgren: Few fixes for omaps to enable NAND BCH so devices won't produce errors when booted with omap2plus_defconfig, and reduce bloat by making IPV6 a loadable module. Also let's add a warning about legacy boot being deprecated for omap3. We now have things working with device tree, and only omap3 is still booting in legacy mode. So hopefully this warning will help move the remaining legacy mode users to boot with device tree. As the total reduction of code and static data is somewhere around 20000 lines of code once we remove omap3 legacy mode booting, we really do want to make omap3 to boot also in device tree mode only over the next few merge cycles. * tag 'fixes-against-v3.18-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (407 commits) ARM: OMAP2+: Warn about deprecated legacy booting mode ARM: omap2plus_defconfig: Fix errors with NAND BCH ARM: omap2plus_defconfig: Fix bloat caused by having ipv6 built-in + Linux 3.18-rc2 Signed-off-by: NOlof Johansson <olof@lixom.net>

The sk_prot is irda's own set of protocol handlers, so irda should statically know what that function is anyway, without using an indirect pointer. And as it happens, we know *exactly* what that pointer is statically: it's NULL, because irda doesn't define a disconnect operation. So calling that function is doubly wrong, and will just cause an oops.
