xfs: fix fsmap cursor handling [v2]

Browse source

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
 
 This has been lightly tested with fstests.  Enjoy!
