Darrick J. Wong 3abb2ac959 ext4: limit entries returned when counting fsmap records ... [ Upstream commit af8c53c8bc087459b1aadd4c94805d8272358d79 ] If userspace asked fsmap to try to count the number of entries, we cannot return more than UINT_MAX entries because fmh_entries is u32. Therefore, stop counting if we hit this limit or else we will waste time to return truncated results. Fixes: 0c9ec4beec ("ext4: support GETFSMAP ioctls") Signed-off-by: Darrick J.
