Commit Message

Nirjhar Roy Oct. 22, 2024, 7:26 p.m. UTC
This commit adds new tests that checks the behaviour of xfs/ext4
filesystems when extsize hint is set on file with inode size as 0, non-empty
files with allocated and delalloc extents and so on.
Although currently this test is placed under tests/generic, it
only runs on xfs and there is an ongoing patch series[1] to enable
extsize hints for ext4 as well.

Do these tests work correctly with fsblock size of 64k?  Just curious
since Pankaj just sent a series doing 1M -> 4M bumps to fix quota
issues.

Might want to check that there isn't an extsize/cowextsize set on the
root directory due to mkfs options.

Does this work for filesystems that don't have delalloc?  Like fsdax
filesystems?

Yes I have tested this with 2k, 4k, 16k, 64k on ppc64le and x86_64

We have made some changes in the tests in v2 so that the test behaves as 
expected with preset extsize/extszinherit mkfs options on the root. Also 
tested with  mkfs.xfs from [1]. I will send PATCH v2 shortly.

+# This test verifies that extent allocation hint setting works correctly on files with
+# no extents allocated and non-empty files which are truncated. It also checks that the
+# extent hints setting fails with non-empty file i.e, with any file with allocated
+# extents or delayed allocation. We also check if the extsize value and the
+# xflag bit actually got reflected after setting/re-setting the extsize value.
