Hi Ted
I happened to be going through the source code for write_cache_pages(),
and I came across a reference to AOP_WRITEPAGE_ACTIVATE. I was curious
what the heck that was, so I did search for it, and found this in
Documentation/filesystems/vfs.txt:
If wbc-sync_mode is
The size of reserved space is stored in space_info. If block groups
of different raid types are linked to separate space_info, changing
allocation profile will corrupt reserved space accounting.

This patch also introduces EXTENT_FIRST_DELALLOC control bit for
set/clear_extent_bit. It tells set/clear_bit_hook whether they

AOP_WRITEPAGE_ACTIVATE was introduced for ramdisk and tmpfs thing
(and later rd choosed to use another way).
Then, It assume writepage refusing aren't happen on majority pages.
IOW, the VM assume other many pages can writeout although the page can't.

You can modify line

to
