This patchset has been pending in the erofs mailing list for months.
It mainly focuses on cleaning up io submission flow in the decompression
subsystem in order to remove #ifdefs in related functions, which
were used to differentiate whether cached decompression is enabled
(rather than do in-place decompression only).

These patches has been tested by our Android beta users for these months,
no new issue reported.
