btrfs: Check cancel and pause in interval of scrub operation
Old code checking cancel and pause request inside scrub stripe
operation, like:
loop() {
if (parity) {
scrub_parity_stripe();
continue;
}
check_cancel_and_pause()
scrub_normal_stripe();
}
Reason is when introduce raid56 stripe scrub, new code is inserted
simplely to front of loop.
Better to:
loop() {
check_cancel_and_pause()
if (parity)
scrub_parity_stripe();
else
scrub_normal_stripe();
}
This patch adjusted code place to realize above sequence.
