MDEV-24393 InnoDB disregards --skip-external-locking
On POSIX systems, InnoDB would unconditionally acquire advisory locks on the files that it opens. On Linux, this would be observable by a large number of entries in /proc/locks. Other storage engines would only acquire advisory locks on files based on the Boolean configuration parameter external_locking. Let InnoDB do the same. NOTE: The --skip-external-locking is activated by default. To have InnoDB acquire advisory locks, --external-locking must be specified. Reviewed by: Sergei Golubchik
