Subject: [PATCH v2 0/3] erofs-utils: prepare for per-(sub)file compression strategies
Date: Sat, 22 May 2021 12:34:59 +0800 [thread overview]
Message-ID: <20210522043502.11975-1-xiang@kernel.org> (raw)
Hi all,
This patchset mainly provides a new helper z_erofs_get_max_pclusterblks()
to prepare for per-(sub)file compression strategies, valid pclustersize
can be returned according to detailed data type or access patterns.
In order to do that, compression header is now generated on the per-file
basis as well, which will be also needed for parallel compression in
the future.
randomizing pclusterblks support in debugging mode is also added to
randomize each pcluster size for big pcluster selftest.
Thanks,
Gao Xiang
