Therefore, remove the "select SRCU" Kconfig statements from the various KVM Kconfig files. Signed-off-by: Paul E.

I didn't realize 0cd7e350abc4 ("rcu: Make SRCU mandatory") is already in Linus' tree, i.e. bundling this in a single patch was unnecessary work for you. Anyways, since there isn't an external dependency, this can go through the KVM tree. Unless you prefer to take it directly, I'll make sure Paolo sends it along at some point before v6.2 final. ^ permalink raw reply [flat|nested] 3+ messages in thread

Just let me know when you have it in place, and I will drop my copy on my next rebase after that. Thanx, Paul ^ permalink raw reply [flat|nested] 3+ messages in thread
