Subject: [PATCH 0/2] kernel/module.c locking changes
Date: Mon, 31 May 2010 21:30:15 +0930 [thread overview]
Message-ID: <201005312130.17038.rusty@rustcorp.com.au> (raw)
In-Reply-To: <201005311910.32407.rusty@rustcorp.com.au>
In response to Linus' almost-rational dislike of the lock-drop-and-regrab
patch, I've dug out and updated the fine-grained locking patch for module.c.
Simple testing here seems to work, and it might have a good effect on boot
times too (its original target).
Pull request for those who find that easier:
The following changes since commit 67a3e12b05e055c0415c556a315a3d3eb637e29e:
Linus Torvalds (1):
Linux 2.6.35-rc1
are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6.git modules
Rusty Russell (3):
module: fix reference to mod->percpu after freeing module.
module: make locking more fine-grained.
module: fix bne2 "gave up waiting for init of module libcrc32c"
