[PATCH] ext3: Add "-o bh" option
This patch adds "-o bh" option to force use of buffer_heads. This option is needed when we make "nobh" as default - and if we run into problems. Signed-off-by: Badari Pulavarty <pbadari@us.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
