Subject: [PATCH 14/14] hfsplus: fix rename over directories
Date: Fri, 1 Oct 2010 09:28:11 +0200 [thread overview]
Message-ID: <20101001072811.GN27055@lst.de> (raw)
In-Reply-To: <20101001072500.GA26972@lst.de>
When renaming over a directory we need to use hfsplus_rmdir instead of
hfsplus_unlink to evict the victim. This makes sure we properly error out
on non-empty directory as required by Posix (BZ #16571), and it also makes
sure we do the right thing in case i_nlink will every be set correctly for
directories on hfsplus.
