[PATCH 00/10] fallocate: introduce FALLOC_FL_WRITE_ZEROES flag

[Martin K. Petersen]

Zhang,

> Changes since RFC v4:
>  - Rebase codes on 6.16-rc1.
>  - Add a new queue_limit flag, and change the write_zeroes_unmap sysfs
>    interface to RW mode. User can disable the unmap write zeroes
>    operation by writing '0' to it when the operation is slow.
>  - Modify the documentation of write_zeroes_unmap sysfs interface as
>    Martin suggested.
>  - Remove the statx interface.
>  - Make the bdev and ext4 don't allow to submit FALLOC_FL_WRITE_ZEROES
>    if the block device does not enable the unmap write zeroes operation,
>    it should return -EOPNOTSUPP.

This looks OK to me as long as the fs folks agree on the fallocate()
semantics.
