Series [v2] fstests: add 4Kn support to btrfs tests | expand

Commit Message

Wang Yugui Oct. 16, 2022, 2:43 a.m. UTC 
xfs_io '-b 512' fail on 4Kn device. because '-b bsize' of xfs_io should be
greater than or equal to the sector size of block device.

so replace some 512 with 4096 to support both 4Kn and 512 sector size.

but there are too many dup lines for 4K byte dump, so we use 'uniq' to
remove them. this new _filter_xfs_io_offset_uniq() is based on
_filter_xfs_io_offset() and 'uniq' is added.

other _filter_xfs_io_offset() in test/btrfs could be replaced by
_filter_xfs_io_offset_uniq() too, but we will do this later when necessary.
