NFS needs to be able to release objects that are stored in the page
cache once the page itself is no longer visible from the page cache.

This patch adds a callback to the address space operations that allows
filesystems to perform page cleanups once the page has been removed

Documentation/filesystems/Locking: update documentation on llseek() wrt BKL 2010-05-27T16:12:56+00:00 Jan Blunck jblunck@suse.de 2010-05-26T21:44:54+00:00 866707fc2721df8fee637fcf0239628b9231f9ea The inode's i_size is not protected by the big kernel lock. Therefore it does not make sense to recommend taking the BKL in filesystems llseek operations. Instead it should use the inode's mutex or use just use i_size_read() instead. Add a note that this is not protecting file->f_pos.
