Merge tag 'vfs-6.10.rw' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs rw iterator updates from Christian Brauner:
"The core fs signalfd, userfaultfd, and timerfd subsystems did still
use f_op->read() instead of f_op->read_iter(). Convert them over since
we should aim to get rid of f_op->read() at some point.
Aside from that io_uring and others want to mark files as FMODE_NOWAIT
so it can make use of per-IO nonblocking hints to enable more
efficient IO. Converting those users to f_op->read_iter() allows them
to be marked with FMODE_NOWAIT"
* tag 'vfs-6.10.rw' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
signalfd: convert to ->read_iter()
userfaultfd: convert to ->read_iter()
timerfd: convert to ->read_iter()
new helper: copy_to_iter_full()
