[PATCH v3] xfstests: Btrfs: add test for large metadata blocks
Tests Btrfs filesystems with all possible metadata block sizes, by
setting large extended attributes on files.
Signed-off-by: Koen De Wit <koen.de.wit@oracle.com>
---
v1->v2:
- Fix indentation: 8 spaces instead of 4
- Move _scratch_unmount to end of loop, add _check_scratch_fs
- Sending failure messages of mkfs.btrfs to output instead of
$seqres.full
v2->v3:
- Sending the md5sums of the retrieved attribute values to the
output instead of comparing them to the md5sum of the original
value
- Always testing attribute values of 4, 8, 12, ... up to 64 KB
regardless of the pagesize, to make the golden output independent
of the pagesize
- Sending the output of mkfs.btrfs with illegal leafsize to
$seqres.full and checking the return code
- Using more uniform variable names: pagesize/pagesize_kb, leafsize/
leafsize_kb, attrsize/attrsize_kb
