The branch main has been updated by rmacklem: URL: https://cgit.FreeBSD.org/src/commit/?id=f0c9847a6c477430d6fff647b12e9e9e2b461f2a commit f0c9847a6c477430d6fff647b12e9e9e2b461f2a Author: Rick Macklem <rmacklem@FreeBSD.org> AuthorDate: 2021-11-06 20:26:43 +0000 Commit: Rick Macklem <rmacklem@FreeBSD.org> CommitDate: 2021-11-06 20:26:43 +0000 vfs: Add "ioflag" and "cred" arguments to VOP_ALLOCATE When the NFSv4.2 server does a VOP_ALLOCATE(), it needs the operation to be done for the RPC's credential and not td_ucred. It also needs the writing to be done synchronously. This patch adds "ioflag" and "cred" arguments to VOP_ALLOCATE() and modifies vop_stdallocate() to use these arguments. The VOP_ALLOCATE.9 man page will be patched separately.
