Hi folks, non-tailpacking I/O: https://lore.kernel.org/r/20210712120241.199903-1-hsiangkao@xxxxxxxxxxxxxxxxx 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!
