If pci_iomap() fails in mwifiex_pcie_init(), it breaks off initialization,
deallocates all resources, but returns zero.

When a device was disconnected the driver may hang at waiting for urbs it never
will get. Fix this by using a timeout while waiting for the used semaphore.
There is still a memory leak if a timeout happens, but at least the driver

Well spotted, that appears to suffer from the same ailment. Will cook
up a second patch for that.

the chances of upstreaming the Web10G patch to provide the RFC4898 TCP Extended

Yes, it's a tad on the intrusive side, and there's performance costs attached -
but so are a lot of *other*

We certainly can do that, AFAICT.

Make balance_dirty_pages start the throttling when the WRITEBACK_TEMP
counter is high enough. This prevents us from having too many dirty
pages on fuse, thus giving the userspace part of it a chance to write
stuff properly.
Note, that the existing balance logic is per-bdi, i.e. if the fuse

Introduce a bit kernel and userspace exchange between each-other on
the init stage and turn writeback on if the userspace want this and
mount option 'allow_wbcache' is present (controlled by fusermount).
Also add each writable file into per-inode write list and call the
generic_file_aio_write to
The problem is:
1. write cached data to a file
2. read directly from the same file (via another fd)
The 2nd operation may read stale data, i.e. the one that was in a file
before the 1st op. Problem is in how fuse manages writeback.
When direct op occurs the core kernel code calls
fuse_writepage_locked() should never submit new i/o for given page->index
if there is another one 'in progress' already. In most cases it's safe to
wait on page writeback. But if it was called due to memory shortage
(WB_SYNC_NONE), we should redirty page rather than blocking caller.
The aim of .flush fop is to hint file-system that flushing its state or caches
or any other important data to reliable storage would be desirable now.
fuse_flush() passes this hint by sending FUSE_FLUSH request to userspace.
However, dirty pages and pages under writeback may be not visible to

The .writepages one is required to make each writeback request carry more than
one page on it.
Changed in v2:
- fixed fuse_prepare_write() to avoid reads beyond EOF
- fixed fuse_prepare_write() to zero uninitialized part of page
