Subject: [PATCH][PPC32] fix locking bugs in mv64x60 code
Date: Wed, 02 Feb 2005 17:20:03 -0700 [thread overview]
Message-ID: <42016E33.9070804@mvista.com> (raw)
[Original patch slightly edited by mgreer]
This patch fixes 2 SMP deadlocks. The first is that mv64x60_read() was
returning before the unlock. The second was mv64x60_modify() locks the spin
lock and calls mv64x60_read() and mv64x60_write() which also lock the same spin lock.
Please apply.
