Liu Bo 6e1116a0b3 Btrfs: fix truncate down when no_holes feature is enabled ... [ Upstream commit 91298eec05cd8d4e828cf7ee5d4a6334f70cf69a ] For such a file mapping, [0-4k][hole][8k-12k] In NO_HOLES mode, we don't have the [hole] extent any more. Commit c1aa45759e ("Btrfs: fix shrinking truncate when the no_holes feature is enabled") fixed disk isize not being updated in NO_HOLES mode when data is not flushed. However, even if data has been flushed, we can still have trouble in updating disk isize since we updated disk isize to 'start' of the last evicted extent.
