Christoph Hellwig c0e59e1ac0 xfs: remove the ->kill_root btree operation ... The implementation os ->kill_root only differ by either simply zeroing out the now unused buffer in the btree cursor in the inode allocation btree or using xfs_btree_setbuf in the allocation btree. Initially both of them used xfs_btree_setbuf, but the use in the ialloc btree was removed early on because it interacted badly with xfs_trans_binval. In addition to zeroing out the buffer in the cursor xfs_btree_setbuf updates the bc_ra array in the btree cursor, and calls xfs_trans_brelse on the buffer previous occupying the slot. The bc_ra update should be done for the alloc btree updated too, although the lack of it does not cause serious problems. The xfs_trans_brelse call on the other hand is effectively a no-op in the end - it keeps decrementing the bli_recur refcount until it hits zero, and then just skips out because the buffer will always be dirty at this point. So removing it for the allocation btree is just fine. So unify the code and move it to xfs_btree.c. While we're at it also replace the call to xfs_btree_setbuf with a NULL bp argument in xfs_btree_del_cursor with a direct call to xfs_trans_brelse given that the cursor is beeing freed just after this and the state updates are superflous. After this xfs_btree_setbuf is only used with a non-NULL bp argument and can thus be simplified.
