From: Roberto Sassu <roberto.sassu@huawei.com>

Since IMA is not yet an LSM, don't account for it in the LSM_CONFIG_COUNT
calculation, used to limit how many LSMs can invoke security_add_hooks().

Merged into lsm/dev-staging, thanks!

Welcome!

Could you please also rebase lsm/dev-staging, to move ab3888c7198d
("LSM: wireup Linux Security Module syscalls") after f7875966dc0c
("tools headers UAPI: Sync files changed by new fchmodat2 and
map_shadow_stack syscalls with the kernel sources")?

Thanks

Roberto

Let me look into that, as long as it doesn't blow up the stuff in
lsm/dev (I don't think it would), I'll go ahead and rebase to v6.6-rc4
which should resolve the syscall numbering conflict.

FWIW, I also hit the same problem with my kernel-secnext builds, if
you're using those RPMs you'll find it's already resolved there.

That wasn't very messy so I've rebased lsm/dev-staging to v6.6-rc4 and
regenerated lsm/next.  If you notice any problems please let me know.

Now merged into lsm/dev, thanks Roberto!
