From: Zhang Yi <yi.zhang@huawei.com> Changes since v2: - In patch 3, update the chang log as Jan suggested. - In patch 5 and 6, when moving reserved blocks count updating to ext4_es_insert_extent(), chang the condition for determining quota claim by passing allocation information instead of counting used reserved blocks as Jan suggested. - Add patch 9, drop an unused helper ext4_es_store_status(). - Add patch 10, make extent status type exclusive, add assertion and commtents as Jan suggested. Changes since v1: - Just rebase to v6.11-rc1. 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 improvements of commit messages. This series is based on 6.11-rc3, after it we could save a lot of code. 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 7-12 make extent status type exclusive and drop the unused code (e.g. ext4_es_is_delonly()), update comments and do some cleanup.
