Here's another update of this patch queue on top of v5.15-rc5. Changes: * Fix a bug in the do_promote changes of "gfs2: Clean up function may_grant" (find_first_holder needs to be called inside the restart loop). * Add a comment explaining __iomap_dio_rw's new done_before argument per request of Darrick J. Wong. * Use untagged_addr() in fault_in_safe_writeable as per comment from Catalin Marinas. I've pushed is patch set here: https://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2.git/log/?h=for-next.mmap-fault b01b2d72da25c000aeb124bc78daf3fb998be2b6 These changes are from October 25, so they've had some exposure in for-next. As Stephen Rothwell points out, there's a minor merge conflict between commit: bb523b406c84 ("gup: Turn fault_in_pages_{readable,writeable} into fault_in_{readable,writeable}") from this patch set and the following two commits in mainline: fcfb7163329c ("x86/fpu/signal: Move xstate clearing out of copy_fpregs_to_sigframe()") a2a8fd9a3efd ("x86/fpu/signal: Change return code of restore_fpregs_from_user() to boolean") Thanks, Andreas Andreas Gruenbacher (16): iov_iter: Fix iov_iter_get_pages{,_alloc} page fault return value powerpc/kvm: Fix kvm_use_magic_page gup: Turn fault_in_pages_{readable,writeable} into fault_in_{readable,writeable} iov_iter: Turn iov_iter_fault_in_readable into fault_in_iov_iter_readable iov_iter: Introduce fault_in_iov_iter_writeable gfs2: Add wrapper for iomap_file_buffered_write gfs2: Clean up function may_grant gfs2: Move the inode glock locking to gfs2_file_buffered_write gfs2: Eliminate ip->i_gh gfs2: Fix mmap + page fault deadlocks for buffered I/O iomap: Fix iomap_dio_rw return value for user copies iomap: Support partial direct I/O on user copy failures iomap: Add done_before argument to iomap_dio_rw gup: Introduce FOLL_NOFAULT flag to disable page faults iov_iter: Introduce nofault flag to disable page faults gfs2: Fix mmap + page fault deadlocks for direct I/O Bob Peterson (1): gfs2: Introduce flag for glock holder auto-demotion arch/powerpc/kernel/kvm.c | 3 +- arch/powerpc/kernel/signal_32.c | 4 +- arch/powerpc/kernel/signal_64.c | 2 +- arch/x86/kernel/fpu/signal.c | 7 +- drivers/gpu/drm/armada/armada_gem.c | 7 +- fs/btrfs/file.c | 7 +- fs/btrfs/ioctl.c | 5 +- fs/erofs/data.c | 2 +- fs/ext4/file.c | 5 +- fs/f2fs/file.c | 2 +- fs/fuse/file.c | 2 +- fs/gfs2/bmap.c | 60 +---- fs/gfs2/file.c | 252 +++++++++++++++++++-- fs/gfs2/glock.c | 330 +++++++++++++++++++++------- fs/gfs2/glock.h | 20 ++ fs/gfs2/incore.h | 4 +- fs/iomap/buffered-io.c | 2 +- fs/iomap/direct-io.c | 29 ++- fs/ntfs/file.c | 2 +- fs/ntfs3/file.c | 2 +- fs/xfs/xfs_file.c | 6 +- fs/zonefs/super.c | 4 +- include/linux/iomap.h | 11 +- include/linux/mm.h | 3 +- include/linux/pagemap.h | 58 +---- include/linux/uio.h | 4 +- lib/iov_iter.c | 103 +++++++-- mm/filemap.c | 4 +- mm/gup.c | 139 +++++++++++- 29 files changed, 793 insertions(+), 286 deletions(-) -- 2.31.1
