This patch series is the part 3 prepartory changes of the buffered IO iomap conversion, it simplify the counting and updating logic of delalloc reserved blocks. I picked them out from my buffered IO iomap conversion RFC series v4[1], and did some minor change log messages improvement. It's based on the part 2 prepartory series [2] (not merged yet) + 6.10-rc1. Patch 1-3 simplify the delalloc extent management logic by changes to always set EXT4_GET_BLOCKS_DELALLOC_RESERVE flag when allocating preallocated blocks, and don't add EXTENT_STATUS_DELAYED flag to an unwritten extent, which means ext4_es_is_delayed() is equal to ext4_es_is_delonly(). Patch 4-6 simplify the reserved blocks updating logic by moves the reserved blocks updating from ext4_{ind|ext}_map_blocks() to ext4_es_insert_extent(). Patch 7-10 drop the unused code (e.g. ext4_es_is_delonly())and update comments. This series has passed through kvm-xfstests in auto mode many times, please take a look at it.
