Implement the ->writepages address space operation. This is very
similar to fuse_writepage(), but batches multiple pages into a single
request.
It reuses the fuse_fill_data structure currently used by
fuse_readpages().

Up to now, file writes were split into page size WRITE requests. This
is inefficient, since there are two context switches per request.
So allow bigger writes, but still do it synchronously. Asynchronous

Add a per-filesystem limit for the number of dirty pages. If half the

Each WRITE request must carry a valid file descriptor. When a page is
written back from a memory mapping, the file through which the page
was dirtied is not available, so a new mechananism is needed to find a
suitable file in ->writepage(s).

A new flag for WRITE requests is also added which indicates that this

The function do_lo_send_aops() should call
balance_dirty_pages_ratelimited() after each page similarly to

This deadlock is similar to the one in balance_dirty_pages, but
instead of waiting in balance_dirty_pages after submitting a write

Set the read and write congestion state if the request queue is close
to blocking, and clear it when it's not.
This prevents unnecessary blocking in readahead and writeback.

I ran "make ARCH=x86_64 menuconfig", did a lot of editing, and saved
the .config. Then I copied that to a backup, ran "make oldconfig" on the
config I'd just saved, and compared it with the backup:

I have this message in the dmesg on a mail server running on an xfs
