Subject: bcache: kthread don't set writeback task to INTERUPTIBLE
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f665c0f852316ff99e9eb7f71f34d43003f8e139;p=linux.git

bcache: kthread don't set writeback task to INTERUPTIBLE

at the beginning (schedule_timout_interuptible) and others
do his on their own

This prevents wrong load average calculation (load of 1 per thread)
