[PATCHSET v1.0 0/2] xfs: widen EFI format to support rt

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

 



Hi all,

Realtime reverse mapping (and beyond that, realtime reflink) needs to be
able to defer file mapping and extent freeing work in much the same
manner as is required on the data volume.  Make the extent freeing log
items operate on rt extents in preparation for realtime rmap.

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.
