/*
|
|
* Various page->flags bits:
|
|
*
|
|
* PG_reserved is set for special pages, which can never be swapped out. Some
|
|
* of them might not even exist (eg empty_bad_page)...
|
|
*
|
|
* The PG_private bitflag is set on pagecache pages if they contain filesystem
|
|
* specific data (which is normally at page->private). It can be used by
|
|
* private allocations for its own usage.
|
|
*
|
|
* During initiation of disk I/O, PG_locked is set. This bit is set before I/O
|
|
* and cleared when writeback _starts_ or when read _completes_. PG_writeback
|
|
* is set before writeback starts and cleared when it finishes.
|
|
*
|
|
* PG_locked also pins a page in pagecache, and blocks truncation of the file
|
|
* while it is held.
|
|
*
|
|
* page_waitqueue(page) is a wait queue of all tasks waiting for the page
|
|
* to become unlocked.
|
|
*
|
|
* PG_uptodate tells whether the page's contents is valid. When a read
|
|
* completes, the page becomes uptodate, unless a disk I/O error happened.
|
|
*
|
|
* PG_referenced, PG_reclaim are used for page reclaim for anonymous and
|
|
* file-backed pagecache (see mm/vmscan.c).
|
|
*
|
|
* PG_error is set to indicate that an I/O error occurred on this page.
|
|
*
|
|
* PG_arch_1 is an architecture specific page state bit. The generic code
|
|
* guarantees that this bit is cleared for a page when it first is entered into
|
|
* the page cache.
|
|
*
|
|
* PG_highmem pages are not permanently mapped into the kernel virtual address
|
|
* space, they need to be kmapped separately for doing IO on the pages. The
|
|
* struct page (these bits with information) are always mapped into kernel
|
|
* address space...
|
|
*
|
|
* PG_hwpoison indicates that a page got corrupted in hardware and contains
|
|
* data with incorrect ECC bits that triggered a machine check. Accessing is
|
|
* not safe since it may cause another machine check. Don't touch!
|

|
|
|
|
/*
|
|
* Don't use the *_dontuse flags. Use the macros. Otherwise you'll break
|
|
* locked- and dirty-page accounting.
|
|
*
|
|
* The page flags field is split into two parts, the main flags area
|
|
* which extends from the low bits upwards, and the fields area which
|
|
* extends from the high bits downwards.

|
|
* SPARSEMEM_EXTREME with !SPARSEMEM_VMEMMAP).
