bash/2294 is trying to acquire lock:
(&journal->j_list_lock){--..}, at: [<c01eee2f>] journal_try_to_free_buffers+0x76/0x10c

but task is already holding lock:
(inode_lock){--..}, at: [<c01864b6>] drop_pagecache+0x48/0xd8

which lock already depends on the new lock.

Andrew, drop_pagecache() is root-only and it has some known deadlock, 
right?
