Subject: [GIT PULL] fuse fixes for 5.15-rc7

Hi Linus,

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git tags/fuse-fixes-5.15-rc7

Syzbot discovered a race in case of reusing the fuse sb (introduced in this
cycle).  Fix by doing the s_fs_info initialization at the proper place.

Thanks,
Miklos

----------------------------------------------------------------
Miklos Szeredi (5):
      fuse: check s_root when destroying sb
      fuse: get rid of fuse_put_super()
      fuse: clean up fuse_mount destruction
      fuse: always initialize sb->s_fs_info
      fuse: clean up error exits in fuse_fill_super()
