Merge patch series "credential guards: credential preparation"
Christian Brauner <brauner@kernel.org> says:
This converts most users combining
* prepare_creds()
* modify new creds
* override_creds()
* revert_creds()
* put_cred()
to rely on credentials guards.
* patches from https://patch.msgid.link/20251103-work-creds-guards-prepare_creds-v1-0-b447b82f2c9b@kernel.org:
trace: use override credential guard
trace: use prepare credential guard
coredump: use override credential guard
coredump: use prepare credential guard
coredump: split out do_coredump() from vfs_coredump()
coredump: mark struct mm_struct as const
coredump: pass struct linux_binfmt as const
coredump: move revert_cred() before coredump_cleanup()
sev-dev: use override credential guards
sev-dev: use prepare credential guard
sev-dev: use guard for path
cred: add prepare credential guard
