Description Kotresh HR 2022-09-09 10:51:28 UTC

Description of problem:
The 'size' shown in the output of snapshot info command relies on rstats which
is incorrect snapshot size. It tracks size of the subvolume from the
snapshot has been taken instead of the snapshot itself. Hence having the
'size' field in the output of 'snapshot info' doesn't make sense until the
rstats is fixed.

Please check attached upstream tracker for more information.
