Maybe, but I can't seem to build perf at all for quite a while, so I
doubt that anyone really cares here, right?
We're building perf and it worked before these patches. It's part of our
kernel build and we do ship the result to customers. So we care :-)
We can choose one of the three ways to solve this :
1. Drop this patch and resolve conflicts in the next patch by keeping
pthread_mutex_*, but this might not help future backports.
Let me just drop all of the perf patches for now from 5.15 and then I'll
take some tested backports if really needed.
Sounds good, thanks. We'll have a look at backports.
Otherwise, why not just use perf from the latest 6.9 tree?
We have a build pipeline that's set up to build everything from the same
source tree and it's not really feasible to mix and match versions like
that -- besides, we don't want to jump from 5.15 to 6.9 for this stuff
any more than we do for the kernel itself.
Thanks,
