Subject: [GIT PULL] vfs fixes

Hey Linus,

/* Summary */
This contains three fixes:

* Get rid of copy_mc flag in iov_iter which really only makes sense for
  the core dumping code so move it out of the generic iov iter code and
  make it coredump's problem. See the detailed commit description.
* Revert fs/aio: Make io_cancel() generate completions again
  The initial fix here was predicated on the assumption that calling
  ki_cancel() didn't complete aio requests. However, that turned out to
  be wrong since the two drivers that actually make use of this set
  a cancellation function that performs the cancellation correctly.
  So revert this change.
* Ensure that the test for IOCB_AIO_RW always happens before the read
  from ki_ctx.

/* Testing */
clang: Debian clang version 16.0.6 (19)
gcc: (Debian 13.2.0-7) 13.2.0

All patches are based on v6.8-rc7 and have been sitting in linux-next.
No build failures or warnings were observed.

/* Conflicts */
At the time of creating this PR no merge conflicts were reported from
linux-next and no merge conflicts showed up doing a test-merge with
current mainline.
