[GIT PULL] vfs rw

Hey Linus,

/* Summary */
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.

/* Testing */
clang: Debian clang version 16.0.6 (26)
gcc: (Debian 13.2.0-24)

All patches are based on v6.9-rc3 and have been sitting in linux-next.
No build failures or warnings were observed.

/* Conflicts */

No known conflicts.
