> include/linux/spinlock.h includes spin_unlock_wait() to wait for a concurrent
> holder of a lock. this patch just moves over to that API. spin_unlock_wait
> covers both raw_spinlock_t and spinlock_t so it should be safe here as well.
> the added rt-variant of read_seqbegin in include/linux/seqlock.h that is being
> modified, was introduced by patch:
> seqlock-prevent-rt-starvation.patch
>
> patch is on top of 3.12.1-rt4
>
> behavior should be unchanged.
Applied. One note: you indented the comment by one space. It looked to
me like cited to complete commit. Please do commit-id ("one line
description) and avoid the one line space at the begin of everyline if
possible.
