macroUPL_CHECK_DIRTY

upl pages check flags

#define UPL_CHECK_DIRTY 0x1

macroUPL_IOSYNC

upl pagein/pageout flags when I/O is issued from this UPL it should be done synchronously

#define UPL_IOSYNC 0x1

macroUPL_NOCOMMIT

the passed in UPL should not have either a commit or abort applied to it by the underlying layers... the site that created the UPL is responsible for cleaning it up.

#define UPL_NOCOMMIT 0x2

macroUPL_NORDAHEAD

turn off any speculative read-ahead applied at the I/O layer

#define UPL_NORDAHEAD 0x4

macroUPL_VNODE_PAGER

#define UPL_VNODE_PAGER 0x8

macroUPL_MSYNC

this pageout is being originated as part of an explicit memory synchronization operation... no speculative clustering should be applied, only the range specified should be pushed.

#define UPL_MSYNC 0x10

macroUPL_PAGING_ENCRYPTED

#define UPL_PAGING_ENCRYPTED 0x20

this pageout is being originated as part of an explicit memory synchronization operation that is checking for I/O errors and taking it's own action... if an error occurs, just abort the pages back into the cache unchanged

#define UPL_KEEPCACHED 0x40

macroUPL_NESTED_PAGEOUT

this pageout originated from within cluster_io to deal with a dirty page that hasn't yet been seen by the FS that backs it... tag it so that the FS can take the appropriate action w/r to its locking model since the pageout will reenter the FS for the same file currently being handled in this context.

#define UPL_NESTED_PAGEOUT 0x80

macroUPL_IOSTREAMING

we've detected a sequential access pattern and we are speculatively and aggressively pulling pages in... do not count these as real PAGEINs w/r to our hard throttle maintenance

#define UPL_IOSTREAMING 0x100

macroUPL_IGNORE_VALID_PAGE_CHECK

Currently, it's only used for the swap pagein path. Since the swap + compressed pager layer manage their pages, these pages are not marked "absent" i.e. these are "valid" pages. The pagein path will _not_ issue an I/O (correctly) for valid pages. So, this flag is used to override that logic in the vnode I/O path.

#define UPL_IGNORE_VALID_PAGE_CHECK 0x200

macroUPL_COMMIT_FREE_ON_EMPTY

upl commit flags

#define UPL_COMMIT_FREE_ON_EMPTY 0x1

#define UPL_DEV_MEMORY 0x1

macroUPL_PHYS_CONTIG

macroUPL_POP_DIRTY

Flags for the UPL page ops routine. This routine is not exported out of the kernel at the moment and so the defs live here.

macroUPL_ROP_ABSENT

Flags for the UPL range op routine. This routine is not exported out of the kernel at the moemet and so the defs live here. UPL_ROP_ABSENT: Returns the extent of the range presented which is absent, starting with the start address presented

#define UPL_ROP_ABSENT 0x01

macroUPL_ROP_PRESENT

UPL_ROP_PRESENT: Returns the extent of the range presented which is present (i.e. resident), starting with the start address presented

#define UPL_ROP_PRESENT 0x02

macroUPL_ROP_DUMP

UPL_ROP_DUMP: Dump the pages which are found in the target object for the target range.

#define UPL_ROP_DUMP 0x04
