Re: [PATCH] checkpatch: Add warnings for use of mdelay()

[Dan Carpenter]

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...
