Subject: [GIT PULL] Btrfs fixes for 6.18-rc3

Hi,

please pull a few btrfs fixes. Thanks.

- in send, fix duplicated rmdir operations when using extrefs
  (hardlinks), receive can fail with ENOENT

- fixup of error check when reading extent root in ref-verify and
  damaged roots are allowed by mount option (found by smatch)

- fix freeing partially initialized fs info (found by syzkaller)

- fix use-after-free when printing ref_tracking status of delayed inodes
