Some page flags are stored in page_type rather than ->flags field. Use newly introduced page type %pGt in dump_page(). Below are some examples: page:00000000da7184dd refcount:1 mapcount:0 mapping:0000000000000000 index:0x0 pfn:0x101cb3 flags: 0x2ffff0000000000(node=0|zone=2|lastcpupid=0xffff) page_type: 0xffffffff() raw: 02ffff0000000000 0000000000000000 dead000000000122 0000000000000000 raw: 0000000000000000 0000000000000000 00000001ffffffff 0000000000000000 page dumped because: newly allocated page page:00000000da7184dd refcount:0 mapcount:-128 mapping:0000000000000000 index:0x0 pfn:0x101cb3 flags: 0x2ffff0000000000(node=0|zone=2|lastcpupid=0xffff) page_type: 0xffffff7f(buddy) raw: 02ffff0000000000 ffff88813fff8e80 ffff88813fff8e80 0000000000000000 raw: 0000000000000000 0000000000000000 00000000ffffff7f 0000000000000000 page dumped because: freed page page:0000000042202316 refcount:3 mapcount:2 mapping:0000000000000000 index:0x7f634722a pfn:0x11994e memcg:ffff888100135000 anon flags: 0x2ffff0000080024(uptodate|active|swapbacked|node=0|zone=2|lastcpupid=0xffff) page_type: 0x1() raw: 02ffff0000080024 0000000000000000 dead000000000122 ffff8881193398f1 raw: 00000007f634722a 0000000000000000 0000000300000001 ffff888100135000 page dumped because: user-mapped page Link: https://lkml.kernel.org/r/20230130042514.2418-4-42.hyeyoo@gmail.com Signed-off-by: Hyeonggon Yoo <42.hyeyoo@gmail.com> Cc: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Cc: David Hildenbrand <david@redhat.com> Cc: Joe Perches <joe@perches.com> Cc: John Ogness <john.ogness@linutronix.de> Cc: Matthew Wilcox <willy@infradead.org> Cc: Petr Mladek <pmladek@suse.com> Cc: Sergey Senozhatsky <senozhatsky@chromium.org> Cc: Steven Rostedt (Google) <rostedt@goodmis.org> Cc: Vlastimil Babka <vbabka@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
