hi Linus-
this patch is a pre-requisite for NFS direct I/O support (which many would
like to see in 2.5/6), and is being awaited by the raw dev guys. please
apply this to 2.5.40.
this patch adds a "struct file *" argument to direct I/O. this is needed
by NFS direct I/O to make the file's credentials available to direct I/O
subroutines. we can't remove "struct inode *" yet because the raw driver
still needs it.
andrew, trond, and the raw dev team are OK with this patch.
