Subject: s3: VFS: vfs_extd_audit. Implement unlinkat().
X-Git-Tag: talloc-2.3.1~643
X-Git-Url: http://git.samba.org/?a=commitdiff_plain;h=0c16e77ae1ea0ef565c66e24297031db0b114710;p=samba.git

s3: VFS: vfs_extd_audit. Implement unlinkat().

This is identical to unlink(), as there
are no special cases needed for rmdir().
