[SRU][J:gcp/gke, N:gcp/gke/gkeop][PATCH 0/5] Revert: "IDPF: TX timeout and crash"

[Ian Whitfield]

BugLink: https://bugs.launchpad.net/bugs/2093622

[Impact]

This patchset previously requested by Google has been found to cause
crashes without a dependency commit:
e4891e4687c8 ("idpf: split &idpf_queue into 4 strictly-typed queue structures")
This requires a rework of the patchset, so we need to pull it from the
current cycle until further notice.

[Fix]

The patchset is reverted for all affected kernels. Another email was
sent for the Oracular version of the patchset.

Kernel owners applying this patchset should replace the commit message
with their specific commit hashes or otherwise re-do the reverts to get
correct hashes, keeping the ACK lines from this thread.

[Where problems could occur]

Reverting this fix reintroduces the problems originally intended to be
solved by the patchset, but prevents new major crashes and should
generally be a net benefit to stability of the kernel. These kernels
will go through normal rounds of testing for the cycle.
