Subject: Fix for genalloc locking
Date: Fri, 17 Oct 2008 16:43:12 +1000 [thread overview]
Message-ID: <48F83400.90901@call-direct.com.au> (raw)
Hi,
I hit a little problem while using genalloc with a mix
of interrupt/non-interrupt context. I believe the correct
fix is to replace the locking calls with the _irqsave/_irqrestore
variants. Patch follows.
Is this correct?
BTW, is there any documentation on the Lockdep warnings?
What exactly is the meaning of {--+.} in
(&pool->lock){--+.}, at: [<c0125d1c>] gen_pool_free+0x34/0x120
Kind regards,
Iwo
