[PATCHSET v2 0/1] xfs: fix fsmap cursor handling

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


Hi all,

This patchset addresses an integer overflow bug that Dave Chinner found
in how fsmap handles figuring out where in the record set we left off
when userspace calls back after the first call filled up all the
designated record space.

v2: add RVB tags

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

This has been running on the djcloud for months with no problems.  Enjoy!
Comments and questions are, as always, welcome.
