    SubjectRe: 2.6.33-rc0: reiserfs: inconsistent lock state
    From
    One more warning.
    This is No space left situation.

    [ INFO: possible circular locking dependency detected ]
    2.6.32-06486-g053fe57 #2
    -------------------------------------------------------
    vi/23454 is trying to acquire lock:
    (&journal->j_mutex){+.+...}, at: [<c110dac4>] do_journal_begin_r+0x64/0x2f0

    but task is already holding lock:
    (&REISERFS_SB(s)->lock){+.+.+.}, at: [<c11106a8>] reiserfs_write_lock+0x28/0x40

    which lock already depends on the new lock.


    the existing dependency chain (in reverse order) is:

    -> #1 (&REISERFS_SB(s)->lock){+.+.+.}:
    [<c104f8f3>] validate_chain+0xa23/0xf70

    other info that might help us debug this:

    2 locks held by vi/23454:
    #0: (&sb->s_type->i_mutex_key#5){+.+.+.}, at: [<c109d64e>]
    do_filp_open+0x27e/0x920
    #1: (&REISERFS_SB(s)->lock){+.+.+.}, at: [<c11106a8>]
