[Gluster-Maintainers] [Gluster-devel] Brick-Mux tests failing for over 11+ weeks

[Shyam Ranganathan]

After various analysis and fixes here is the current state,

- Reverted 3 patches aimed at proper cleanup sequence when a mux'd brick
is detached [2]
- Fixed a core within the same patch, for a lookup before brick is ready
case
- Fixed an replicate test case, that was partly failing due to cleanup
sequence and partly due to replicate issues [3]

Current status is that we are still tracking some failures using this
[1] bug and running on demand brick-mux regressions on Jenkins.

State of 4.0 release is almost even with 4.1, with the fixes/changes
above, but it is not yet in the clear to continue with 4.1 release.

Request any help that can be provided to Mohit, Du and Milind who are
currently looking at this actively.
