| |
The first 3 patches provide a new lockdep check, it verifies we don't hold any locks when returning to userspace.
lockdep-sys_exit.patch lockdep-i386-sys_exit.patch lockdep-x86_64-sys_exit.patch
Could the various arch maintainers that have support for lockdep help out with placing this hook?
A journal_start annotation:
jbd-lock.patch
Up until this point stuff should be safe to merge (assuming there are no objections and bugs.. :-)
The rest of the series annotates lock_page():
rework lock_page() API: trylock_page.patch lock_page.patch lockdep-page_lock-hooks.patch
actuall lockdep annotation: lockdep-depth.patch lockdep-fs-page.patch lockdep-page-async.patch set_page_mapping.patch lockdep-lock_page.patch
Part of that is re-working the lock_page() API a bit. It introduces trylock_page(), and removes all the raw *PageLock() usage.
I've compile and boot tested this series on x86_64 (with and without lockdep). And it completes an LTP run with lockdep enabled.
Andrew, can we start by pusing the lock_page() API rework into -mm?
[ this series is against -linus, but if you're willing I'll do some patches against -mm ]
