mainline inclusion from mainline-v5.14-rc4 commit 04fcad80cd068731a779fb442f78234732683755 category: bugfix bugzilla: 187526,https://gitee.com/openeuler/kernel/issues/I6WKVJ
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
--------------------------------
Introduce a helper function xfs_buf_daddr() to extract the disk address of the buffer from the struct xfs_buf. This will replace direct accesses to bp->b_bn and bp->b_maps[0].bm_bn, as well as the XFS_BUF_ADDR() macro.
This patch introduces the helper function and replaces all uses of XFS_BUF_ADDR() as this is just a simple sed replacement.
