rhashtable_try_insert | |
do_IRQ | do_IRQ handles all normal device IRQ's (the special* SMP cross-CPU interrupts have their own specific* handlers). |

rdt_cdp_peer_get | dt_cdp_peer_get - Retrieve CDP peer if it exists*@r: RDT resource to which RDT domain @d belongs*@d: Cache instance for which a CDP peer is requested*@r_cdp: RDT resource that shares hardware with @r (RDT resource peer)* Used to return the result |
rdtgroup_mondata_show | |
rdtgroup_pseudo_lock_create | dtgroup_pseudo_lock_create - Create a pseudo-locked region*@rdtgrp: resource group to which pseudo-lock region belongs* Called when a resource group in the pseudo-locksetup mode receives a* valid schemata that should be pseudo-locked |

break_ksm | We use break_ksm to break COW on a ksm page: it's a stripped down* if (get_user_pages(addr, 1, 1, 1, &page, NULL) == 1)* put_page(page);* but taking great care only to touch a ksm page, in a VM_MERGEABLE vma, |

khugepaged_do_scan | |
kmemleak_update_trace | kmemleak_update_trace - update object allocation stack trace*@ptr: pointer to beginning of the object* Override the object allocation stack trace for cases where the actual* allocation place is not always useful. |
