The branch main has been updated by mhorne: URL: https://cgit.FreeBSD.org/src/commit/?id=5df74441b35f2303ecdc7b79f9d331f5e77a07db commit 5df74441b35f2303ecdc7b79f9d331f5e77a07db Author: Mitchell Horne <mhorne@FreeBSD.org> AuthorDate: 2024-06-04 23:17:47 +0000 Commit: Mitchell Horne <mhorne@FreeBSD.org> CommitDate: 2024-06-04 23:17:47 +0000 devmap: eliminate unused arguments The optional 'table' pointer is a legacy part of the interface, which has been replaced by devmap_register_table()/devmap_add_entry(). The few in-tree callers have already adapted to this, so it can be removed. The 'l1pt' argument is already entirely unused within the function.
