Current SHPCHP driver uses msleep_interruptible() function to wait for a command completion event. But I think this would cause an unnecessary long wait until timeout, if command completion interrupt came before task state was changed to TASK_INTERRUPTIBLE. This patch fixes this issue. With this patch, command completion becomes faster as follows: o Without this patch # time echo 1 > power real 0m4.708s user 0m0.000s sys 0m0.524s o With this patch # time echo 1 > power real 0m2.221s user 0m0.000s sys 0m0.532s Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> |
