Caller| Name | Describe |
|---|
| lock_page_maybe_drop_mmap | lock_page_maybe_drop_mmap - lock the page, possibly dropping the mmap_sem*@vmf - the vm_fault for this fault.*@page - the page to lock.*@fpin - the pointer to the file we may pin (or is already pinned). |
| do_sync_mmap_readahead | Synchronous readahead happens when we don't even find a page in the page* cache at all. We don't want to perform IO under the mmap sem, so if we have* to drop the mmap sem we return the file that was pinned in order for us to do* that |
| do_async_mmap_readahead | Asynchronous readahead happens when we find the page and PG_readahead,* so we want to possibly extend the readahead further. We return the file that* was pinned if we have to drop the mmap_sem in order to do IO. |
| filemap_fault | lemap_fault - read in file data for page fault handling*@vmf: struct vm_fault containing details of the fault* filemap_fault() is invoked via the vma operations vector for a* mapped memory region to read in file data during a page fault |
| fault_dirty_shared_page | Handle dirtying of a page in shared file mapping on a write fault.* The function expects the page to be locked and unlocks it. |
