[PATCH 15/37] drivers/gpu/drm: Use kmemdup
From: Julia Lawall <julia(a)diku.dk> Use kmemdup when some other buffer is immediately copied into the allocated region. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression from,to,size,flag; statement S; @@ - to = \(kmal... 15 May 2010 18:05

[PATCH 04/10] cdc-acm: remove dead code
The wait_event_interruptible_timeout in acm_port_down is never reached. Remove it to avoid possible deadlocks with the big tty mutex if someone were to start using the blocking version of acm_port_down.

[PATCH v3 00/10] BKL conversion in tty layer
This is the third attempt to get the BKL out of the TTY code. This version goes much further than the previous one, and eliminates most of the code I had introduced there. What remains of the series are changes to the existing BKL usage in the TTY layer to avoid depending on the autorelease-during-sleep or the... 15 May 2010 18:05

[PATCH 03/10] tty: fix console_sem lock order
vgacon_do_font_op releases and reacquires the BTM while holding console_sem. This violates the rule that BTM has to be the outer lock whenever we hold both. There does not seem to be any reason to give up the BTM here, so just stop doing that. Signed-off-by: Arnd Bergmann <arnd(a)arndb.de> --- drivers/video/c... 15 May 2010 18:05

[PATCH 07/10] tty: reorder ldisc locking
We need to release the BTM in paste_selection() when sleeping in tty_ldisc_ref_wait to avoid deadlocks with tty_ldisc_enable. In tty_set_ldisc, we now always grab the BTM before taking the ldisc_mutex in order to avoid AB-BA deadlocks between the two. tty_ldisc_halt potentially blocks on a workqueue function... 15 May 2010 18:05
