[GIT PULL] iomap: bug fix for 5.7-rc3

[Darrick J. Wong]

Hi Linus,

Please pull this single bug fix for 5.7 that hoists 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.  The branch merged cleanly with upstream head
as of a few minutes ago.

--D

  fibmap: Warn and return an error in case of block > INT_MAX (2020-04-30 07:57:46 -0700)

----------------------------------------------------------------
Changes for 5.7:
- Move the FIBMAP range check and warning out of the backend iomap
implementation and into the frontend ioctl_fibmap so that the checking
is consistent for all implementations.
