[PATCHSET RFC v1.1 0/8] xfs: clean up realtime type usage

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

 



Hi all,

The realtime code uses xfs_rtblock_t and xfs_fsblock_t in a lot of
places, and it's very confusing.  Clean up all the type usage so that an
xfs_rtblock_t is always a block within the realtime volume, an
xfs_fileoff_t is always a file offset within a realtime metadata file,
and an xfs_rtxnumber_t is always a rt extent within the realtime volume.

v1.1: various cleanups suggested by hch

If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.

With a bit of luck, this should all go splendidly.
Comments and questions are, as always, welcome.
