  "title": "xfs: don\u0027t hold buffer locks across sync transaction commit in xfs_sync_sb_buf",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  xfs: don\u0027t hold buffer locks across sync transaction commit in xfs_sync_sb_buf  xfs_sync_sb_buf() holds sb/rtsb buffer locks across a synchronous xfs_trans_commit(), which flushes the CIL push workqueue internally. If shutdown occurs during the CIL push, xfs_buf_item_unpin() needs to lock these buffers to fail them, causing a deadlock:    setlabel:          holds buf lock -\u003E flush_workqueue(xfs-cil)   CIL push worker:   xfs_buf_item_unpin -\u003E xfs_buf_lock(same buf)  Remove the xfs_trans_bhold() calls so that commit releases the buffer locks normally.  After the sync commit, re-acquire the buffers via mp-\u003Em_sb_bp / mp-\u003Em_rtsb_bp for the on-disk writeback.",
