The inode cache is saved in the FS tree itself for every individual FS tree, that affects the sizes reported by qgroup show so we need to explicitly turn it off to get consistent values. Thanks,
Right, so we need turn off inode_cache explicitly rather than free_space
option.
I will fix all your addressed comments and resend the patch.
Thanks,

Test flow is to run fsstress after triggering quota rescan.
the ruler is simple, we just remove all files and directories,
sync filesystem and see if qgroup's ref and excl are nodesize.

Add "-o nospace_cache" here please, otherwise I don't get the same
output.
I am little confused why we need specify this mount option explicitly?
As far as i know, space cache is not included into qgroup accounting
space.
It is. Thanks,
Free space cache are inserted in tree root, they can not be shared with
other trees(fs/file tree).
So normal fs/file tree's qgroup accounting is independeng of free space
cache.
With or without the option, subvolume qgroup's value should not have any
differences.
Did i miss something here?:-)
Thanks,
Wang
