RE: Mutex and Sleep

Hi,
What I find here in the kernel/mutex.c:86 is that there is a function
__sched_mutex_lock in which I find might_sleep function call on line no. 86,
which implies that if no lock is acquired it would sleep till it gets it.
I am a bit surprised about you having no sleep nor delay there. I assume,
you are on the 2.6 kernel.

Subject: Mutex and Sleep

Hello all,

Could anyone explain me a bit about sleeping inside mutex_locks???
afaik this shouldn't be a problem... but I'm getting a "BUG: sleeping
function called from invalid context at kernel/mutex.c:86"

I have no sleep() nor delay() inside the function it's complaining
about. So I'm kind of stuck here.


Thanks in advance
