Subject: nobh mount option in ext3/4?
Date: Mon, 31 May 2010 14:40:51 +0200 [thread overview]
Message-ID: <20100531124051.GA17262@lst.de> (raw)
ext3 and ext4 heave inherited the nobh option from ext2, but the
implementation is rather interesting. Except for the usual
option parsing / display it's only respected in
ext3_writeback_writepage/ext4_writepage and the truncate_page
implementation. Given that we don't take any more than usual
care to not create buffers heads during read this is not going
to effect a whole lot.
Is there a good reason to keep these options and the associated
code complexity? I'd be rather surprised if it gets any sufficient
testing..
