SRU Justification:
[Impact]
* The xfs filesystem suffers from a deadlock issue in kernels < 5.5. This hangs IO to/from the affected filesystem.
[Fix]
* 93597ae8dac0149b5c00b787cba6bf7ba213e666 93597ae8dac0 "xfs: Fix deadlock between AGI and AGF when target_ip exists in xfs_rename()"
[Test Plan]
* Set up an Ubuntu Bionic/Focal installation using kernel 5.4.
* Create and mount an XFS filesystem on a block device.
* Exercise the filesystem to verify that IO does not hang.
[Where problems could occur]
* This patch could cause locking issues on XFS filesystems, requiring a system restart to correct.
[Other Info]
* Bug is difficult to reproduce, a test kernel on affected systems with the above patch prevented the issue. |

[Other Info]
* Bug is difficult to reproduce, a test kernel on affected systems with the above patch prevented the issue.
* Backports to earlier (4.15 and earlier) kernels have been omitted as the upstream patch does not apply cleanly and the issue has not been reproduced on them. |
