| H A D | Kconfig | a08e67a0 Wed Aug 04 19:35:59 CDT 2021 Huang Jianan <huangjianan@oppo.com> erofs: iomap support for non-tailpacking DIO
Add iomap support for non-tailpacking uncompressed data in order to
support DIO and DAX.
Direct I/O is useful in certain scenarios for uncompressed files.
For example, double pagecache can be avoid by direct I/O when
loop device is used for uncompressed files containing upper layer
compressed filesystem.
This adds iomap DIO support for non-tailpacking cases first and
tail-packing inline files are handled in the follow-up patch.
