Subject: [PATCH 7/8] nilfs2: do not use yield()
Date: Thu,  2 Jun 2016 22:58:10 +0900
Message-ID: <1464875891-5443-8-git-send-email-konishi.ryusuke@lab.ntt.co.jp> (raw)
In-Reply-To: <1464875891-5443-1-git-send-email-konishi.ryusuke@lab.ntt.co.jp>

Use cond_resched() instead of yield() in the loop of
nilfs_transaction_lock() since the usage corresponds to the "be nice
for others" case that the comment of yield() says.

This removes the following checkpatch.pl warning:

 "WARNING: Using yield() is generally wrong. See yield() kernel-doc
  (sched/core.c)"
