VGET(9) BSD Kernel Manual VGET(9)
vget - get a vnode from the free list
#include <sys/param.h> #include <sys/vnode.h> int vget(struct vnode *vp, int flags, struct proc *p);
Get a vnode from the free list and increment its reference count. Its arguments are: vp The vnode to remove from the free list. flags If non-zero, the vnode will also be locked. p The process responsible for this call. When not in use, vnodes are kept on a free list. The vnodes still refer- ence valid files but may be reused to refer to a new file at any time. Often, these vnodes are also held in caches in the system, such as the name cache. When a vnode which is on the free list is used again, for instance if the vnode was found in the name cache as a result of a call to VOP_LOOKUP(9), then the new user must call vget() to increment the reference count and remove it from the free list.
[ENOENT] The vnode vp is in the process of being cleaned out from the underlying file system.
