Mark Lord 0de1517e23 [PATCH] Fix 2.6.21 rfcomm lockups ... Any attempt to open/use a bluetooth rfcomm device locks up scheduling completely on my machine. Interrupts (ping, alt-sysrq) seem to be alive, but nothing else. This was working fine in 2.6.20, broken now in 2.6.21-rc2-git* Reverting this change (below) fixes it: | author Marcel Holtmann <marcel@holtmann.org> | Sat, 17 Feb 2007 22:58:57 +0000 (23:58 +0100) | committer David S. Miller <davem@sunset.davemloft.net> | Mon, 26 Feb 2007 19:42:41 +0000 (11:42 -0800) | commit c1a3313698 | tree 337a876f72 tree | snapshot | parent f5ffd4620a commit | diff | | [Bluetooth] Make use of device_move() for RFCOMM TTY devices | | In the case of bound RFCOMM TTY devices the parent is not available | before its usage. So when opening a RFCOMM TTY device, move it to | the corresponding ACL device as a child. When closing the device, | move it back to the virtual device tree. | Signed-off-by: Marcel Holtmann <marcel@holtmann.org> The simplest fix for this bug is to prevent sysfs_move_dir() from self-deadlocking when (old_parent == new_parent). This patch prevents total system lockup when using rfcomm devices.
