PCI, vmd: Reinstate VMD driver inadvertently removed by SRCU updates (!3440) · Merge requests · Red Hat / centos-stream / src / kernel / centos-stream-9

Myron Stowe requested to merge mstowe1/centos-stream-9:redhat/j16633 into main Dec 03, 2023

Upstream recently removed the Sleepable Read-Copy Update (SRCU) Kconfig
option (re: merge commits 8cc01d43f882 and 5dfb75e842e0; note included
commit e035e8876e6c "rcu: Remove CONFIG_SRCU").  During the back-port of
this removal series, a key patch was missed which ends up inhibiting the
ability to ever enable the Volume Management Driver (VMD) despite an
intention of such by supplying a build related '.config' file that includes
VMD's set configuration entry ("CONFIG_VMD=y").

This series resolves JIRA ticket 16633 "VMD connected drives are not visible
in system", by back-porting the missed upstream commit a8f0ff9185ae
"drivers/pci/controller: Remove "select SRCU"", thereby reinstating the
ability to include the VMD driver with the kernel.
