Merge tag 'sysctl-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl
Pull sysctl update from Joel Granados:
- Avoid evaluating non-mount ctl_tables as a sysctl_mount_point by
removing the unlikely (but possible) chance that the permanently
empty ctl_table array shares its address with another ctl_table
- Update Joel Granados' contact info in MAINTAINERS
* tag 'sysctl-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl:
MAINTAINERS: update email for Joel Granados
sysctl: avoid spurious permanent empty tables
