Date: Sat, 30 Mar 2024 20:02:29 +0800 From: Zhang Yi <yi.zhang@...weicloud.com> To: linux-ext4@...r.kernel.org Cc: linux-fsdevel@...r.kernel.org, tytso@....edu, adilger.kernel@...ger.ca, jack@...e.cz, yi.zhang@...wei.com, yi.zhang@...weicloud.com, chengzhihao1@...wei.com, yukuai3@...wei.com Subject: [PATCH 0/7] ext4: support adding multi-delalloc blocks From: Zhang Yi <yi.zhang@...wei.com> 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], and add bigalloc feature support. The first 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. This patch set has been passed 'kvm-xfstests -g auto' tests, I hope it could be reviewed and merged first.
