[PATCH] quota: reiserfs: improve quota credit estimates
Use improved credits estimates for quota operations. Also reserve space for a quota operation in a transaction only if filesystem was mounted with some quota option. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
