So, the most urgent thing is solving the warning messages. With these fixes, most warning messages in dax_associate_entry() are gone. But honestly, generic/388 will randomly failed with the warning. The case shutdown the xfs when fsstress is running, and do it for many times. I think the reason is that dax pages in use are not able to be invalidated in time when fs is shutdown. The next time dax page to be associated, it still remains the mapping value set last time. I'll keep on solving it. The warning message in dax_writeback_one() can also be fixed because of the dax unshare. This patch (of 8): fsdax page is used not only when CoW, but also mapread. To make the it easily understood, use 'share' to indicate that the dax page is shared by more than one extent. And add helper functions to use it. Also, the flag needs to be renamed to PAGE_MAPPING_DAX_SHARED.

The case shutdown the xfs when fsstress is running, and do it for many times. I think the reason is that dax pages in use are not able to be invalidated in time when fs is shutdown. The next time dax page to be associated, it still remains the mapping value set last time. I'll keep on solving it. The warning message in dax_writeback_one() can also be fixed because of the dax unshare. This patch (of 8): fsdax page is used not only when CoW, but also mapread. To make it easily understood, use 'share' to indicate that the dax page is shared by more than one extent. And add helper functions to use it. Also, the flag needs to be renamed to PAGE_MAPPING_DAX_SHARED.

The case shutdown the xfs when fsstress is running, and do it for many times. I think the reason is that dax pages in use are not able to be invalidated in time when fs is shutdown. The next time dax page to be associated, it still remains the mapping value set last time. I'll keep on solving it. The warning message in dax_writeback_one() can also be fixed because of the dax unshare. This patch (of 8): fsdax page is used not only when CoW, but also mapread. To make it easily understood, use 'share' to indicate that the dax page is shared by more than one extent. And add helper functions to use it. Also, the flag needs to be renamed to PAGE_MAPPING_DAX_SHARED.

The case shutdown the xfs when fsstress is running, and do it for many times. I think the reason is that dax pages in use are not able to be invalidated in time when fs is shutdown. The next time dax page to be associated, it still remains the mapping value set last time. I'll keep on solving it. The warning message in dax_writeback_one() can also be fixed because of the dax unshare. This patch (of 8): fsdax page is used not only when CoW, but also mapread. To make the it easily understood, use 'share' to indicate that the dax page is shared by more than one extent. And add helper functions to use it. Also, the flag needs to be renamed to PAGE_MAPPING_DAX_SHARED.
