From bcb48891b05b4179edc86298d3dccb2ce90d5413 Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Fri, 27 Mar 2009 02:51:39 +0900 Subject: [PATCH] nilfs2: fix lockdep recursive locking warning on bmap The bmap semaphore of DAT file can be held while a bmap of other files is locked. This has caused the following false detection of lockdep check: mount.nilfs2/4667 is trying to acquire lock: (&bmap->b_sem){..--}, at: [] nilfs_bmap_lookup_at_level+0x1a/0x74 [nilfs2] but task is already holding lock: (&bmap->b_sem){..--}, at: [] nilfs_bmap_lookup_at_level+0x1a/0x74 [nilfs2] This will fix the false detection by distinguishing semaphores of the DAT and other files.
