[GIT PULL] overlayfs fixes for 4.8-rc4

Show all headers | View raw

Hi Linus,

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git overlayfs-linus

Most of this is regression fixes for posix acl behavior introduced in
4.8-rc1 (these were caught by the pjd-fstest suite).  The are also
miscellaneous fixes marked as stable material and cleanups.

Other than overlayfs code, it touches <linux/fs.h> to add a constant with
which to disable posix acl caching.  No changes needed to the actual
caching code, it automatically does the right thing, although later we may
want to optimize this case.

I'm now testing overlayfs with the following test suites to catch
regressions:

 - unionmount-testsuite
 - xfstests
 - pjd-fstest

Thanks,
Miklos
