Subject: s3: VFS: vfs_time_audit. Implement unlinkat().
X-Git-Tag: talloc-2.3.1~626
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b355a9565dcf67304db12aa827ca582d1dd80b89;p=thirdparty%2Fsamba.git

s3: VFS: vfs_time_audit. Implement unlinkat().

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