It is somewhat similar to madvise(2) except that it operates on a file descriptor instead of a memory region. It is currently only supported on regular files. Note that this adds a new VOP, so all filesystem modules must be recompiled.

The default implementation in vop_stdallocate() is filesystem agnostic and will run as slow as a read/write loop in userspace; however, it serves to correctly implement the functionality for filesystems that do not implement a VOP_ALLOCATE. Allow VOP_ALLOCATE to be iterative, and have kern_posix_fallocate(9) drive looping and potentially yielding.

Valid struct ucred is needed for audit and MAC, and curthread credentials may be wrong. This further requires modifying the interface of vn_fullpath(9), but it is out of scope of this change.

Since our new NFSv4 client and server can't use it for their requirements, GC the old mechanism, as well as other unused lease- related code and interfaces. Due to its impact on kernel programming and binary interfaces, this change should not be MFC'd.

Currently this is used to enable shared locks for open() and close() of read-only file descriptors. - When an ISOPEN namei() request is performed with LOCKSHARED, use a shared vnode lock for the leaf vnode only if the mount point has the extended shared flag set. - Set LOCKSHARED in vn_open_cred() for requests that specify O_RDONLY but not O_CREAT. - Use a shared vnode lock around VOP_CLOSE() if the file was opened with O_RDONLY and the mountpoint has the extended shared flag set. - Adjust md(4) to upgrade the vnode lock on the vnode it gets back from vn_open() since it now may only have a shared vnode lock. - Don't enable shared vnode locks on FIFO vnodes in ZFS and UFS since FIFO's require exclusive vnode locks for their open() and close() routines. (My recent MPSAFE patches for UDF and cd9660 already included this change.) - Enable extended shared operations on UFS, cd9660, and UDF.
