X-Git-Tag: firefly_0821_release~3680^2~2871
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7e5cb5e151c5474b4a468f437f5038ba9f67ef4d;p=firefly-linux-kernel-4.4.55.git

Merge branch 'vfs-cleanups' (random vfs cleanups)

This teaches vfs_fstat() to use the appropriate f[get|put]_light
functions, allowing it to avoid some unnecessary locking for the common
case.

More noticeably, it also cleans up and simplifies the "getname_flags()"
function, which now relies on the architecture strncpy_from_user() doing
all the user access checks properly, instead of hacking around the fact
that on x86 it didn't use to do it right (see commit 92ae03f2ef99: "x86:
merge 32/64-bit versions of 'strncpy_from_user()' and speed it up").

* vfs-cleanups:
  VFS: make vfs_fstat() use f[get|put]_light()
  VFS: clean up and simplify getname_flags()
  x86: make word-at-a-time strncpy_from_user clear bytes at the end
