[PATCH RFC tip/core/rcu 02/23] rcu: add __rcu API for later sparse checking
This commit defines an __rcu API, but provides only vacuous definitions for it. This breaks dependencies among most of the subsequent patches, allowing them to reach mainline asynchronously via whatever trees are appropriate.

[PATCH RFC tip/core/rcu 05/23] mce: convert to rcu_dereference_index_check()
The mce processing applies rcu_dereference_check() to integers used as array indices. This patch therefore moves mce to the new RCU API rcu_dereference_index_check() that avoids the sparse processing that would otherwise result in compiler errors. Signed-off-by: Paul E.

[PATCH RFC tip/core/rcu 07/23] rculist: avoid __rcu annotations
From: Arnd Bergmann <arnd(a)arndb.de> This avoids warnings from missing __rcu annotations in the rculist implementation, making it possible to use the same lists in both RCU and non-RCU cases. We can add rculist annotations later, together with lockdep support for rculist, which is missing as well, but that may... 12 May 2010 18:06

[RFC] new ->perform_write fop
Hello, I just started adding aio_write to Btrfs and I noticed we're duplicating _alot_ of the generic stuff in mm/filemap.c, even though the only thing thats really unique is the fact that we copy userspace pages in chunks rather than one page a t a time. What would be best is instead of doing write_begin/write_... 12 May 2010 18:06
