Caller
NameDescribe
__set_page_dirty_nobuffersFor address_spaces which do not use buffers. Just tag the page as dirty in* the xarray.* This is also used when a single buffer is being dirtied: we want to set the* page dirty in that case, but not all the buffers. This is a "bottom-up"
page_huge_activeTest to determine whether the hugepage is "active/in-use" (i.e. being linked* to hstate->hugepage_activelist.)* This function can be called for tail pages, but never returns true for them.
__free_huge_page
restore_reserve_on_errorThis routine is called to restore a reservation on error paths
