| # FS QA Test No. 456 |
| # |
| # This test is motivated by a bug found in ext4 during random crash |
| # consistency tests. |
| # |
| # Fixed by commit 51e3ae81ec58 ("ext4: fix interaction between i_size, |
| # fallocate, and delalloc after a crash") |
| # |
| # This is also a regression test for ext4 bug that zero range can beyond |
| # i_disksize and fixed by commit 801674f34ecf ("ext4: do not zeroout extents |
| # beyond i_disksize"). |
