This series mainly aims at adding some of those test cases for testing
fast_commit. Kernel fix for Patch-1 is still under review [1].
RFC -> PATCHv1:
================
1. Patch-1 mostly remains the same.
2. Added ext4/057 & ext4/058 in the test bucket for fast_commit which are based
on recent kernel fixes done by Xin Yin.
[RFC]: https://lore.kernel.org/all/b834b83720f61a6aaab11fe20c48b75007be0a46.1643642943.git.riteshh@linux.ibm.com/

Ritesh Harjani (4):
ext4/056: Add fast_commit regression test causing data abort exception
common/punch: Add block_size argument to _filter_fiemap_**
ext4/057: Add crash test to check unwritten extents tracking with fast_commit
ext4/058: Add shutdown recovery test with fast_commit

fast_commit in certain cases as discussed in the corresponding kernel
commit may miss to track the unwritten extents. This patch add a test
case around that (based on test case shared in kernel commit)
