Hello,
Please find the v2 of this patch series which addresses the review comments from
Jan on PATCH-2 & PATCH-7. No changes other than that.
Summary
========
This patch series aimes at fixing some of the issues identified in fast_commit
with flex_bg. This also adds some stricter checking of blocks to be freed in
ext4_mb_clear_bb(), ext4_group_add_blocks() & ext4_mb_mark_bb()
Testing
=========
I have run xfstests with -g log,metadata,auto group with 4k & 4k_fc
configs. I have not found any regression due to these patches alone.
But I have found few issues like generic/047 occasionally failing even w/o this
patch series. I do have some fixes for those too in my tree. I will send those
fixes later after figuring out few more things around couple other failures.
