Value passed to rpc_madvise()

Enum Values

RPC_MADV_NORMAL

No special treatment

RPC_MADV_RANDOM

Expect page references in random order

RPC_MADV_SEQUENTIAL

Expect page references in sequential order

RPC_MADV_WILLNEED

Expect access in the near future

RPC_MADV_DONTNEED

Do not expect access in the near future

RPC_MADV_REMOVE

Free up a given range of pages and its associated backing store

RPC_MADV_DONTFORK

Pages should not be available to a child after fork()

RPC_MADV_DOFORK

Undo effect of RPC_MADV_DONTFORK

RPC_MADV_HWPOISON

Poison the pages (so that references to them will be handled like a hardware memory corruption)

RPC_MADV_MERGEABLE

Enable Kernel Samepage Merging

RPC_MADV_UNMERGEABLE

Undo the effect of RPC_MADV_MERGEABLE

RPC_MADV_SOFT_OFFLINE

Soft offline the pages

RPC_MADV_HUGEPAGE

Enable Transparent Huge Pages

RPC_MADV_NOHUGEPAGE

Ensure that pages will not be collapsed into huge pages

RPC_MADV_DONTDUMP

Exclude pages from a core dump

RPC_MADV_DODUMP

Undo the effect of RPC_MADV_DONTDUMP

RPC_MADV_FREE

The application no longer requires these pages, kernel can free them

RPC_MADV_WIPEONFORK

After fork() a child will find these pages zero-filled

RPC_MADV_KEEPONFORK

Undo the effect of RPC_MADV_WIPEONFORK

RPC_MADV_UNKNOWN

Unknown value
