NAME

       invalidate_mapping_pages - Invalidate all the unlocked pages of one inode

SYNOPSIS

       unsigned long invalidate_mapping_pages(struct address_space * mapping, pgoff_t start, pgoff_t end);

ARGUMENTS

       mapping
	   the address_space which holds the pages to invalidate

       start
	   the offset 'from' which to invalidate

       end
	   the offset 'to' which to invalidate (inclusive)

DESCRIPTION

       This function only removes the unlocked pages, if you want to remove all the pages of one inode, you must call truncate_inode_pages.

       invalidate_mapping_pages will not block on IO activity. It will not invalidate pages which are dirty, locked, under writeback or mapped
       into pagetables.

NAME

     vm_map_clean -- push dirty pages to their pager

SYNOPSIS

     #include <sys/param.h>
     #include <vm/vm.h>
     #include <vm/vm_map.h>

     int
     vm_map_clean(vm_map_t map, vm_offset_t start, vm_offset_t end, boolean_t syncio, boolean_t invalidate);

DESCRIPTION

     The vm_map_clean() function forces any dirty cached pages in the range start to end within the map to be pushed to their underlying pager.

     If syncio is TRUE, dirty pages are written synchronously.

     If invalidate is TRUE, any cached pages are also freed.

     The range provided must be contiguous, it MUST NOT contain holes.	The range provided MUST NOT contain any sub-map entries.

IMPLEMENTATION NOTES

     This routine holds the Giant lock to prevent multiple entry.

RETURN VALUES

     The vm_map_clean() function returns KERN_SUCCESS if successful.

     Otherwise, KERN_INVALID_ADDRESS will be returned if the function encountered a sub-map entry; KERN_INVALID_ARGUMENT will be returned if the
     function encountered a hole in the region provided, or if an entry could not be found for the given start address.
