Hi folks,

non-tailpacking I/O: https://lore.kernel.org/r/20210712120241.199903-1-hsiangkao@linux.alibaba.com

This patchset is a follow-up patchset of the previous patchset and
interacts with iomap itself, whcih mainly adds preliminary EROFS iomap
support for all tackpacking inline cases and has been preliminary
tested myself.

It only covers iomap read path. The write path remains untouched and
bail out with -EIO if inline data with pos != 0 since EROFS cannot be
used for actual testing. It'd be better to be implemented if upcoming
fs users care rather than leave untested dead code around in kernel.
 
Hopefully [PATCH 1/2] could be landed in iomap for-next independently
since it has few changes / iomap-specific and the rest patches can be
rebased upon iomap for-next then.

Comments are welcome. Thanks for your time on reading this!

Thanks,
Gao Xiang
