2.6.20-rc3 produces the following lockdep warning when hald is
started during system startup:
=============================================
[ INFO: possible recursive locking detected ]
2.6.20-rc3-noinitrd #0
---------------------------------------------
hald-subfs-moun/4608 is trying to acquire lock:
(&inode->i_mutex){--..}, at: [<c035bb02>] mutex_lock+0x1c/0x1f
but task is already holding lock:
(&inode->i_mutex){--..}, at: [<c035bb02>] mutex_lock+0x1c/0x1f
other info that might help us debug this:
3 locks held by hald-subfs-moun/4608:

=======================
I guess it's really the same ReiserFS issue I already reported for
the previous releases, just triggered at an earlier point in the
system's life.
Other than that, everything seems fine and dandy on this plain old P3.
HTH, and Happy New Year everyone
