# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'iomap-5.7-fixes-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
#     
#     Pull iomap fix from Darrick Wong:
#      "Hoist the check for an unrepresentable FIBMAP return value into
#       ioctl_fibmap.
#     
#       The internal kernel function can handle 64-bit values (and is needed
#       to fix a regression on ext4 + jbd2). It is only the userspace ioctl
#       that is so old that it cannot deal"
