Merge tag 'xfs-6.2-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs fixes from Darrick Wong:

 - Remove some incorrect assertions

 - Fix compiler warnings about variables that could be static

 - Fix an off by one error when computing the maximum btree height that
   can cause repair failures

 - Fix the bulkstat-single ioctl not returning the root inode when asked
   to do that

 - Convey NOFS state to inodegc workers to avoid recursion in reclaim

 - Fix unnecessary variable initializations

 - Fix a bug that could result in corruption of the busy extent tree
