[SRU][Q:linux-oracle][PATCH 0/1] oracle: backport "sunrpc: allocate a separate bvec array for socket sends" to 6.17

[Vinicius Peixoto]

BugLink: https://bugs.launchpad.net/bugs/2147073

[Impact]

Some OCI customers have been experiencing performance degradation on NFS mounts due to a known issue that has been fixed upstream in 6.19

[Fix]

Backport the following commit from upstream into the Questing linux-oracle tree:
6b3b697d65d4 ("sunrpc: allocate a separate bvec array for socket sends")

[Test plan]

The patch has been compiled-tested only, and since no reproducer is easily available, Oracle will validate the fix with the relevant customers on their side.

[Where problems could occur]

This patch has a small regression risk, and any problems related to it would manifest themselves as crashes or performance issues for users running I/O heavy workloads on NFS mounts.
