VFREE(9)                            Memory Management in Linux                           VFREE(9)



NAME
       vfree - release memory allocated by vmalloc

SYNOPSIS
       void vfree(const void * addr);

ARGUMENTS
       addr
           memory base address

DESCRIPTION
       Free the virtually continuous memory area starting at addr, as obtained from vmalloc,
       vmalloc_32 or __vmalloc. If addr is NULL, no operation is performed.

       Must not be called in NMI context (strictly speaking, only if we don't have
       CONFIG_ARCH_HAVE_NMI_SAFE_CMPXCHG, but making the calling conventions for vfree
       arch-depenedent would be a really bad idea)

NOTE
       assumes that the object at *addr has a size >= sizeof(llist_node)
