Subject: [PATCH v2 0/9] 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], 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 2 patches fix an incorrect delalloc reserved blocks count
issue, 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.
