From: Peter Hurley Date: Fri, 23 Apr 2010 23:27:25 +0000 (-0400) Subject: firewire: core: Fix tlabel exhaustion problem X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=753a8970f68594ea69c5fc13fbca18dbd9402996;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git firewire: core: Fix tlabel exhaustion problem fw_core_handle_response() was not properly clearing tlabel_mask. This was resulting in premature tlabel exhaustion. Signed-off-by: Peter Hurley This fixes an omission in 2.6.31-rc1 commit 1e626fdc "firewire: core: use more outbound tlabels" which prevented to really use 64 instead of 32 transaction labels, as soon as split transactions occurred that had their AR-resp tasklet run after the AT-req tasklet.
