Subject: [PATCH 0/7] ext4: support adding multi-delalloc blocks

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.

Thanks,
Yi.
