NAME¶
vfree - release memory allocated by vmallocSYNOPSIS¶
void
vfree(const void * addr);
ARGUMENTS¶
addrmemory 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)COPYRIGHT¶
