Expand description
Usage information for a range of memory to allow for performance optimizations by the kernel.
Used by madvise
.
Variants
No further special treatment. This is the default.
Expect random page references.
Expect sequential page references.
Expect access in the near future.
Do not expect access in the near future.
Free up a given range of pages and its associated backing store.
Do not make pages in this range available to the child after a fork(2)
.
Undo the effect of MADV_DONTFORK
.
Poison the given pages.
Subsequent references to those pages are treated like hardware memory corruption.
Enable Kernel Samepage Merging (KSM) for the given pages.
Undo the effect of MADV_MERGEABLE
Preserve the memory of each page but offline the original page.
Enable Transparent Huge Pages (THP) for pages in the given range.
Undo the effect of MADV_HUGEPAGE
.
Exclude the given range from a core dump.
Undo the effect of an earlier MADV_DONTDUMP
.
Specify that the application no longer needs the pages in the given range.
