nilfs2: fix lockdep warning between regular file and inode file
This will fix the following false positive of recursive locking which
lockdep has detected:
=============================================
[ INFO: possible recursive locking detected ]
2.6.30-nilfs #42
---------------------------------------------
nilfs_cleanerd/10607 is trying to acquire lock:
(&bmap->b_sem){++++-.}, at: [<e0d025b7>] nilfs_bmap_lookup_at_level+0x1a/0x74 [nilfs2]
but task is already holding lock:
(&bmap->b_sem){++++-.}, at: [<e0d024e0>] nilfs_bmap_truncate+0x19/0x6a [nilfs2]
other info that might help us debug this:
2 locks held by nilfs_cleanerd/10607:
#0: (&nilfs->ns_segctor_sem){++++.+}, at: [<e0d0d75a>] nilfs_transaction_begin+0xb6/0x10c [nilfs2]
#1: (&bmap->b_sem){++++-.}, at: [<e0d024e0>] nilfs_bmap_truncate+0x19/0x6a [nilfs2]
