Hi,

more regression fixes and stabilization. Please pull, thanks.

Regressions:

- zoned mode
  - count zone sizes in wider int types
  - fix space accounting for read-only block groups

- subpage: fix page tail zeroing

Fixes:

- fix spurious warning when remounting with free space tree

- fix warning when creating a directory with smack enabled

- ioctl checks for qgroup inheritance when creating a snapshot

- qgroup
  - fix missing unlock on error path in zero range
  - fix amount of released reservation on error
  - fix flushing from unsafe context with open transaction, potentially
    deadlocking

- minor build warning fixes
