Subject: [PATCH 0/5] proc: export more page flags in /proc/kpageflags (take 4)
Date: Tue, 28 Apr 2009 09:09:07 +0800 [thread overview]
Message-ID: <20090428010907.912554629@intel.com> (raw)
Hi all,
Export 9 more flags to end users (and more for kernel developers):
11. KPF_MMAP (pseudo flag) memory mapped page
12. KPF_ANON (pseudo flag) memory mapped page (anonymous)
13. KPF_SWAPCACHE page is in swap cache
14. KPF_SWAPBACKED page is swap/RAM backed
15. KPF_COMPOUND_HEAD (*)
16. KPF_COMPOUND_TAIL (*)
17. KPF_UNEVICTABLE page is in the unevictable LRU list
18. KPF_HWPOISON hardware detected corruption
19. KPF_NOPAGE (pseudo flag) no page frame at the address
(*) For compound pages, exporting _both_ head/tail info enables
users to tell where a compound page starts/ends, and its order.
Please check the documentary patch and changelog of the final patch
for the details.
