Subject: [PATCH v3 0/7] gfs2: Fix mmap + page fault deadlocks
Date: Fri, 23 Jul 2021 22:58:33 +0200	[thread overview]
Message-ID: <20210723205840.299280-1-agruenba@redhat.com> (raw)

Hi Linus et al.,

here's an update of my gfs2 mmap + page fault fixes (against -rc2).
From my point of view,

  * these two are ready and need to be looked at by Al:

    iov_iter: Introduce fault_in_iov_iter helper
    iov_iter: Introduce noio flag to disable page faults

  * these two need to be reviewed by Christoph at least:

    iomap: Fix iomap_dio_rw return value for user copies
    iomap: Support restarting direct I/O requests after user copy failures

Thanks a lot,
Andreas
