Subject: Re: [PATCH] checkpatch: Add warnings for use of mdelay()
Date: Thu, 5 Jul 2018 11:19:53 +0300 [thread overview]
Message-ID: <20180705081953.pmvpmtzm273eb6yk@mwanda> (raw)

Neither Smatch nor Coccinelle do a good job tracking when you're in
atomic context. I've wanted to add this to Smatch but even then it
would be to warn that "We're holding a spinlock so we can't sleep".
It's trickier to say for sure when you're not holding a lock...
regards,
dan carpenter
