10 Userfaults allow the implementation of on-demand paging from userland
38 Vmas are not suitable for page- (or hugepage) granular fault tracking

113 - If you requested ``UFFDIO_REGISTER_MODE_MISSING`` when registering then
119 - None of the page-delivering ioctls default to the range that you

166 QEMU/KVM is using the ``userfaultfd`` syscall to implement postcopy live
167 migration. Postcopy live migration is one form of memory
171 KVM kernel code had to be modified in order to add postcopy live
180 It is generally beneficial to run one pass of precopy live migration
181 just before starting postcopy live migration, in order to avoid
184 The implementation of postcopy live migration currently uses one
198 the ``userfaultfd`` and receives the fault address (or ``-EAGAIN`` in case the
215 doesn't need to keep any per-page state bitmap relative to the live
216 migration around and a single per-page bitmap has to be maintained in

281 return ``-ENOSPC`` when the monitored process exits at the time of
282 ``UFFDIO_COPY``, and ``-ENOENT``, when the non-cooperative process has changed
