Subject: [PATCH 0/2] erofs: add fiemap support with iomap
Hi folks,
This patchset mainly addresses fiemap support for EROFS. After this
patchset, end users can observe (un)compressed extent distribution
by hand.
The first patch is also useful for later LZMA support in order to
decompress full LZMA extents if needed (according to specific
strategy.)
Btw, the current development status for LZMA is in the following
branches (yet these are not aimed for the next merge window since
it's still some work to do):
https://git.kernel.org/pub/scm/linux/kernel/git/xiang/linux.git/log/?h=erofs/lzma
https://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs-utils.git/log/?h=experimental-lzma
Thanks,
Gao Xiang
