The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=85656a9a015339f3d412e5b1888e798bb3e7d4ba commit 85656a9a015339f3d412e5b1888e798bb3e7d4ba Author: Warner Losh <imp@FreeBSD.org> AuthorDate: 2024-04-16 22:35:46 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2024-04-17 03:30:17 +0000 nvmecontrol: Make the error log page work on native format As the number of page types proliferates, it becomes untennable to convert them in read_logpage (especailly since new UUID page types will need to be supported). Convert the error page printing code to operate on little endian data.
