Subject: s3: VFS: vfs_full_audit. Implement unlinkat().
X-Git-Tag: talloc-2.3.1~641
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6c28a7749bb8c7c45db86647f5046d2df654653e;p=thirdparty%2Fsamba.git

s3: VFS: vfs_full_audit. Implement unlinkat().

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