Subject: Locking question, is this cool?
Date: Tue, 31 Oct 2000 10:51:53 -0800 [thread overview]
Message-ID: <39FF14C9.33AE7325@mvista.com> (raw)
At line 1073 of ../drivers/char/i2lib.c (2.4.0-test9) we find:
WRITE_LOCK_IRQSAVE(...
this is followed by:
COPY_FROM_USER(...
It seems to me that this could result in a page fault with interrupts
off. Is this ok?
