Hi!
This is the start of the stable review cycle for the 7.2.13 release.
There are 242 patches in this series, all will be posted as a response
to this one. If anyone has any issues with these being applied, please
let me know.
Either something went very wrong with our testing, or this fails on
all our targets. 6.18.59-rc1 does not seem to have those widespread
failures.
https://gitlab.com/cip-project/cip-testing/linux-stable-rc-ci/-/pipelines/2982452623
Example failure is:
I'll look some more to try to figure out what is going on there.
Best regards,
Pavel

Same here indepently, but not yet bisected.
Same here as well, bisected down to: a0c935bd1f76 ("fs: add umh argument to struct kernel_clone_args"), it looks like we need to cherry-pick 14adbd5341aa ("fs: stop sharing fs_struct between init_task and pid 1"), with that I can boot a kernel.
