[Bug 2065856] Re: SEGFAULTs in v4.3 with GlusterFS

[Nick O'Connor]

** Description changed:

  [ Impact ]
  
   * Users experience SEGFAULTs when Ganesha fails to communicate with
  Gluster, causing the NFS share to disappear.
  
   * The patch refactors how free_space() is called to avoid the null
  pointer deference.
  
  [ Test Plan ]
  
   * I experienced crashes about once per day on volumes with heavy large
  file random access. I've been running the proposed patch since
  2024-05-16 and haven't experienced a single crash.
  
+ * The test plan is to run the packages from proposed for at least 5
+ days, under the same load as when the bug happened, and confirm that the
+ crashes reported in this bug no longer happen.
