[RFC PATCH 0/9] Introduce set/clear_fs_page_private to cleanup code

[Guoqing Jiang]

Hi,

Based on the previous thread [1], this patchset introduces set_fs_page_private
and clear_fs_page_private to replace attach_page_buffers and __clear_page_buffers.
Thanks a lot for the constructive suggestion from Matthew and Dave.

And sorry for cross post to different lists since it modifies different subsystems.

Thanks,
Guoqing
