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.
