Hi Chao,
Something like this?
Change log from v3:

This patch introduces a batched trimming feature, which submits split discard
commands.
This is to avoid long latency due to huge trim commands.
If fstrim was triggered ranging from 0 to the end of device, we should

This patch adds checking code whether filesystem supports norecovery mount
option or not.
And let use this into the following xfs test.
xfs/200 (recovery vs ro-block device)
* Currently, norecovery mount option is used by xfs only. But some of log-based
filesystems (e.g., f2fs) are able
Thanks to Dave. :)
Change log from v4:
o add mkfs in _require_scratch_shutdown
o add _require_fiemap and _extent_hole_counts
o add _require_logstate
o modify xfs/086,087 output rules for the generic usage
o add _get_log_configs to introduce consistent testing options
o add _get_quota_option
This patch adds _get_log_configs for xfs and f2fs to test several mount options
for:
xfs/086
* xfs/087
In xfs/087, one more test was added, so 10 tests will be done in total.

This is to detect whether filesystem supports shutdown feature or not.
And let use this into the following xfs tests.

xfs/137 (data vs filesize)
xfs/138 (data vs filesize vs truncate)
xfs/139 (data vs filesize vs partial truncate)

2. introduce universal lookup/update interface of extent cache:

This patch enables rb-tree based extent cache in f2fs.
When we mount with -o extent_cache, f2fs will try to add recently accessed
page-block mappings into rb-tree based extent cache as much as possible, instead
of original one extent info cache.
By this way, f2fs can support more effective cache

patch gives another chance to try to get physical address of page from extent

Rename a filed name from 'blk_addr' to 'blk' in struct {f2fs_extent,extent_info}
as annotation of this field descripts its meaning well to us.
By this way, we can avoid long statement in code of following patches.

This patch adds a fast lookup path for rb-tree extent cache.
In this patch we add a recently accessed extent node pointer 'cached_en' in
