X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a9aefd707c65aa5a7945b3f16bd39f314aa8414d;p=linux-beck.git

GFS2: fix error propagation in init_threads()

If kthread_run() fails, init_threads() returns
IS_ERR(p) instead of PTR_ERR(p).

Found by Linux Driver Verification project (linuxtesting.org).
