[PATCHSET v1.0 0/4] fstests: reflink with large realtime extents

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Now that we've landed support for reflink on the realtime device for
cases where the rt extent size is the same as the fs block size, enhance
the reflink code further to support cases where the rt extent size is a
power-of-two multiple of the fs block size.  This enables us to do data
block sharing (for example) for much larger allocation units by dirtying
pagecache around shared extents and expanding writeback to write back
shared extents fully.

If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.

This is an extraordinary way to destroy everything.  Enjoy!
Comments and questions are, as always, welcome.
