/*
* Mark an inode as being modified, meaning that the caller will modify
* ip->meta.
*
* If a vnode is present we set the vnode dirty and the nominal filesystem
* sync will also handle synchronizing the inode meta-data. If no vnode
* is present we must ensure that the inode is on pmp->sideq.
*
* NOTE: We must always queue the inode to the sideq. This allows H2 to
* shortcut vsyncscan() and flush inodes and their related vnodes
* in a two stages. H2 still calls vfsync() for each vnode.
*
* NOTE: No mtid (modify_tid) is passed into this routine. The caller is
* only modifying the in-memory inode. A modify_tid is synchronized
* later when the inode gets flushed.
*
* NOTE: As an exception to the general rule, the inode MAY be locked
* shared for this particular call.
