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 The following changes since commit 6a8b55ed4056ea5559ebe4f6a4b247f627870d4c: Linux 5.7-rc3 (2020-04-26 13:51:02 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git tags/iomap-5.7-fixes-1 for you to fetch changes up to b75dfde1212991b24b220c3995101c60a7b8ae74: 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. ---------------------------------------------------------------- Ritesh Harjani (1): fibmap: Warn and return an error in case of block > INT_MAX fs/ioctl.c | 8 ++++++++ fs/iomap/fiemap.c | 5 +---- 2 files changed, 9 insertions(+), 4 deletions(-)
