Subject: s3: VFS: vfs_posix_eadb. Implement unlinkat().
X-Git-Tag: talloc-2.3.1~649
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=19c8cfa2871050c857c4ad8eecc8dd0f99cfafdb;p=thirdparty%2Fsamba.git

s3: VFS: vfs_posix_eadb. Implement unlinkat().

Note this isn't identical to unlink() as
this must cope with (flags & AT_REMOVEDIR),
which is identical to rmdir(). It calls
either unlink or rmdir depending on the
flags parameter.
