VFREE(9) | Memory Management in Linux | VFREE(9) |
NAME¶
vfree - release memory allocated by vmalloc
SYNOPSIS¶
void vfree(const void * addr);
ARGUMENTS¶
const void * 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)
