Subject: kernel/irq/proc.c: unprotected iteration over the IRQ action list in name_unique()
X-Git-Tag: v2.6.22-rc1~711
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d2d9433a4c84c9e7ed78d633fdbffb35d5afda17;p=pandora-kernel.git

kernel/irq/proc.c: unprotected iteration over the IRQ action list in name_unique()

setup_irq() releases a desc->lock before calling register_handler_proc(), so
the iteration over the IRQ action list is not protected.

(akpm: the check itself is still racy, but at least it probably won't oops
now).
