#     Merge tag 'iov_iter.3-5.15-2021-09-17' of git://git.kernel.dk/linux-block
#     
#     Pull io_uring iov_iter retry fixes from Jens Axboe:
#      "This adds a helper to save/restore iov_iter state, and modifies
#       io_uring to use it.
#     
#       After that is done, we can now kill the iter->truncated addition that
#       we added for this release. The io_uring change is being overly
#       cautious with the save/restore/advance, but better safe than sorry and
#       we can always improve that and reduce the overhead if it proves to be
#       of concern. The only case to be worried about in this regard is huge
#       IO, where iteration can take a while to iterate segments.
#     
#       I spent some time writing test cases, and expanded the coverage quite
#       a bit from the last posting of this. liburing carries this regression
#       test case now:
#     
#           https://git.kernel.dk/cgit/liburing/tree/test/file-verify.c
#     
#       which exercises all of this. It now also supports provided buffers,
#       and explicitly tests for end-of-file/device truncation as well.
#     
#       On top of that, Pavel sanitized the IOPOLL retry path to follow the
#       exact same pattern as normal IO"
