[PATCH 6.12 0/7] Backport object allocation APIs and two fscrypt fixes

Like I did in an earlier series for 6.18
(https://lore.kernel.org/linux-hardening/[email protected]/),
this series backports kmalloc_obj() et al to 6.12 so that more upstream
commits will cherry-pick cleanly.  As in 6.18, the flex counter
integration isn't included.

Patches 6-7 then backport two fscrypt fixes (which, like lots of other
kernel code, happen to use kzalloc_obj()).  Patch 7 is a clean
cherry-pick, while patch 6 required resolving some other conflicts.

Eric Biggers (2):
  fscrypt: Fix key setup in edge case with multiple data unit sizes
  fscrypt: Replace mk_users keyring with simple list

Kees Cook (2):
  slab: Introduce kmalloc_obj() and family
  slab: Introduce kmalloc_flex() and family

Linus Torvalds (2):
  add default_gfp() helper macro and use it in the new *alloc_obj()
    helpers
  default_gfp(): avoid using the "newfangled" __VA_OPT__ trick

Randy Dunlap (1):
  slab: recognize @GFP parameter as optional in kernel-doc
