I/O targets be kept resident at the same physical address. The
ib_uverbs module manages pinning and unpinning memory regions via
get_user_pages() and put_page() calls. It also accounts for the
- amount of memory pinned in the process's locked_vm, and checks that
+ amount of memory pinned in the process's pinned_vm, and checks that
unprivileged processes do not exceed their RLIMIT_MEMLOCK limit.
Pages that are pinned multiple times are counted each time they are
- pinned, so the value of locked_vm may be an overestimate of the
+ pinned, so the value of pinned_vm may be an overestimate of the
number of pages pinned by a process.
