From: Zhang Yi <yi.zhang@xxxxxxxxxx> Changes since v2: - Improve the commit message in patch 2,4,6 as Ritesh and Jan suggested, makes the changes more clear. - Add patch 3, add a warning if the delalloc counters are still not zero on inactive. - In patch 6, add a WARN in ext4_es_insert_delayed_extent(), strictly requires the end_allocated parameter to be set to false if the inserting extent belongs to one cluster. - In patch 9, modify the reserve blocks math formula as Jan suggested, prevent the count going to be negative. - In patch 10, update the stale ext4_da_map_blocks() function comments. Hello! This patch series is the part 2 prepartory changes of the buffered IO iomap conversion, I picked them out from my buffered IO iomap conversion RFC series v3[1], add a fix for an issue found in current ext4 code, and also add bigalloc feature support. Please look the following patches for details. The first 3 patches fix an incorrect delalloc reserved blocks count issue and add a warning to make it easy to detect, the second 6 patches make ext4_insert_delayed_block() call path support inserting multi-delalloc blocks once a time, and the last patch makes ext4_da_map_blocks() buffer_head unaware, prepared for iomap. This patch set has been passed 'kvm-xfstests -g auto' tests, I hope it could be reviewed and merged first.
