Support segment compression which seperates files in several logic
units (segments) and each segment is compressed independently.
Advantages:
- more friendly for data differencing;
- it can also be used for parallel compression in the same file later.

The cache consistency model of filesystems like gfs2 is such that if
data is found in the page cache, the data is up to date and can be used
without taking any filesystem locks. If a page is not cached,
filesystem locks must be taken before populating the page cache.
Thus far, gfs2 has taken
Hello,
can the two patches in this set still be considered for v5.8?
Commit d4388340ae0b ("fs: convert mpage_readpages to mpage_readahead")
which converts gfs2 and other filesystems to use the new ->readahead
address space operation is leading to deadlocks between the inode glocks
and page
Add an IOCB_CACHED flag which indicates to generic_file_read_iter that
it should only regard the page cache, without triggering any filesystem
I/O for the actual request or for readahead. With this flag, -EAGAIN is
returned when regular I/O would be triggered similar to the IOCB_NOWAIT
flag, and
