Subject: SLEEP_ON_BKLCHECK
Date: Thu, 14 Apr 2005 09:42:30 +0900	[thread overview]
Message-ID: <425DBC76.60804@labs.fujitsu.com> (raw)

Hi,
In Fedora Core3, interruptible_sleep_on() checks if the system is
lock_kernel()'ed
by SLEEP_ON_BKLCHECK. Same thing is done in RedHatEL4.
Also I found a patch including SLEEP_ON_BKLCHECK was posted before,
but is not included in 2.6.11.
Why SLEEP_ON_BKLCHECK checks lock_kernel ? Lock_kernel shoud be held
during sleep_on_timeout? And I also wonder why 2.6.11 does not check it.

Thank you,
