Merge branch 'splice-2.6.23' of git://git.kernel.dk/data/git/linux-2.6-block
* 'splice-2.6.23' of git://git.kernel.dk/data/git/linux-2.6-block:
pipe: add documentation and comments
pipe: change the ->pin() operation to ->confirm()
Remove remnants of sendfile()
xip sendfile removal
splice: completely document external interface with kerneldoc
sendfile: remove bad_sendfile() from bad_file_ops
shmem: convert to using splice instead of sendfile()
relay: use splice_to_pipe() instead of open-coding the pipe loop
pipe: allow passing around of ops private pointer
splice: divorce the splice structure/function definitions from the pipe header
splice: relay support
sendfile: convert nfsd to splice_direct_to_actor()
sendfile: convert nfs to using splice_read()
loop: convert to using splice_direct_to_actor() instead of sendfile()
splice: add void cookie to the actor data
sendfile: kill generic_file_sendfile()
sendfile: remove .sendfile from filesystems that use generic_file_sendfile()
sys_sendfile: switch to using ->splice_read, if available
vmsplice: add vmsplice-to-user support
splice: abstract out actor data
