Expand description
Events from the userfaultfd object that are read by Uffd::read_event()
.
Variants
A pagefault event.
Fields of Pagefault
Generated when the faulting process invokes fork(2)
(or clone(2)
without the CLONE_VM
flag).
Fields of Fork
uffd: Uffd
The Uffd
object created for the child by fork(2)
Generated when the faulting process invokes mremap(2)
.
Fields of Remap
Generated when the faulting process invokes madvise(2)
with MADV_DONTNEED
or
MADV_REMOVE
advice.
Fields of Remove
Generated when the faulting process unmaps a meomry range, either explicitly using
munmap(2)
or implicitly during mmap(2)
or mremap(2)
.
