commit 18f5b477ee66f0e55d6e1badda745b453f9f7bd8 Author: Rick Macklem <[email protected]> AuthorDate: 2021-11-06 20:26:43 +0000 Commit: Rick Macklem <[email protected]> CommitDate: 2021-12-18 22:30:25 +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.
