[PATCH] Fix of quota deadlock on pagelock: reiserfs
Implement quota journaling and quota reading and writing functions for reiserfs. Solves also several other deadlocks possible for reiserfs due to the lock inversion on journal_begin and quota locks. From: Vladimir Saveliev <vs@namesys.com> When CONFIG_QUOTA is defined reiserfs's finish_unfinished sets and clears MS_ACTIVE bit in s_flags field of super block. If that bit was set already it should not be set. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
