We should no longer need the inode->i_lock, now that we've straightened out the request locking. The locking schema is now: 1) Lock page head request 2) Lock the page group 3) Lock the subrequests one by one Note that there is a subtle race with nfs_inode_remove_request() due to the fact that the latter does not lock the page head, when removing it from the struct page. Only the last subrequest is locked, hence we need to re-check that the PagePrivate(page) is still set after we've locked all the subrequests. Signed-off-by:
