return the value instead, and have path_init() do the assignment. Broken by "vfs: Fix absolute RCU path walk failures due to uninitialized seq number", which was Cc-stable with 2.6.38+ as destination. This one should go where it went. To avoid dummy value returned in case when root is already set (it would do no harm, actually, since the only caller that doesn't ignore the return value is guaranteed to have nd->root *not* set, but it's more obvious that way), lift the check into callers. And do the same to set_root(), to keep them in sync. Cc: stable@vger.kernel.org # 2.6.38+ Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

When DYNAMIC_DEBUG enabled, pr_debug() depends on KBUILD_MODNAME which also depends on the modules number in Makefile. The related information in "scripts/Makefile.lib" line 94: # $(modname_flags) #defines KBUILD_MODNAME as the name of the module it will # end up in (or would, if it gets compiled in) # Note: Files that end up in two or more modules are compiled without the # KBUILD_MODNAME definition. The reason is that any made-up name would # differ in different configs. For this case, 'radio-si470x-i2c.o' and 'radio-si470x-common.o' are in one line, so cause compiling issue. And 'uaccess.h' is a common shared header (not specially for drivers), so use pr_devel() instead of is OK.

John W. Linville says: ==================== pull request: wireless 2014-09-05 Please pull this batch of fixes intended for the 3.17 stream... For the mac80211 bits, Johannes says: "Here are a few fixes for mac80211. One has been discussed for a while and adds a terminating NUL-byte to the alpha2 sent to userspace, which shouldn't be necessary but since many places treat it as a string we couldn't move to just sending two bytes. In addition to that, we have two VLAN fixes from Felix, a mesh fix, a fix for the recently introduced RX aggregation offload, a revert for a broken patch (that luckily didn't really cause any harm) and a small fix for alignment in debugfs." For the iwlwifi bits, Emmanuel says: "I revert a patch that disabled CTS to self in dvm because users reported issues. The revert is CCed to stable since the offending patch was sent to stable too. I also bump the firmware API versions since a new firmware is coming up. On top of that, Marcel fixes a bug I introduced while fixing a bug in our Kconfig file."

Commit 0244756e ("ufs: sb mutex merge + mutex_destroy") introduces deadlocks in ufs_new_inode() and ufs_free_inode(). Most callers of that functions acqure the mutex by themselves and ufs_{new,free}_inode() do that via lock_ufs(), i.e we have an unavoidable double lock. The patch proposes to resolve the issue by making sure that ufs_{new,free}_inode() are not called with the mutex held. Found by Linux Driver Verification project (linuxtesting.org).

git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs由 Linus Torvalds 提交于
Pull xfs fixes from Dave Chinner: "The fixes all address recently discovered data corruption issues. The original Direct IO issue was discovered by Chris Mason @ Facebook on a production workload which mixed buffered reads with direct reads and writes IO to the same file. The fix for that exposed other issues with page invalidation (exposed by millions of fsx operations) failing due to dirty buffers beyond EOF. Finally, the collapse_range code could also cause problems due to racing writeback changing the extent map while it was being shifted around. The commits for that problem are simple mitigation fixes that prevent the problem from occuring. A more robust fix for 3.18 that addresses the underlying problem is currently being worked on by Brian. Summary of fixes: - a direct IO read/buffered read data corruption - the associated fallout from the DIO data corruption fix - collapse range bugs that are potential data corruption issues" * tag 'xfs-for-linus-3.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: xfs: trim eofblocks before collapse range xfs: xfs_file_collapse_range is delalloc challenged xfs: don't log inode unless extent shift makes extent modifications xfs: use ranged writeback and invalidation for direct IO xfs: don't zero partial page cache pages during O_DIRECT writes xfs: don't zero partial page cache pages during O_DIRECT writes xfs: don't dirty buffers beyond EOF

The update_walltime() code works on the shadow timekeeper to make the seqcount protected region as short as possible. But that update to the shadow timekeeper does not update all timekeeper fields because it's sufficient to do that once before it becomes life. One of these fields is tkr.base_mono. That stays stale in the shadow timekeeper unless an operation happens which copies the real timekeeper to the shadow. The update function is called after the update calls to vsyscall and pvclock. While not correct, it did not cause any problems because none of the invoked update functions used base_mono. commit cbcf2dd3 (x86: kvm: Make kvm_get_time_and_clockread() nanoseconds based) changed that in the kvm pvclock update function, so the stale mono_base value got used and caused kvm-clock to malfunction. Put the update where it belongs and fix the issue.

The error handling in compat_sys_nanosleep() is correct, but completely non obvious. Document it and restrict it to the -ERESTART_RESTARTBLOCK return value for clarity. Reported-by: NKees Cook <keescook@chromium.org> Signed-off-by: NThomas Gleixner <tglx@linutronix.de>
