Patch 1 is a fix for private mmap in FOPEN_DIRECT_IO mode
This is added here together since the later two depends on it.
Patch 2 is the main dish
Patch 3 is to maintain direct write logic for shared mmap in FOPEN_DIRECT_IO mode
v2 -> v3
add patch 1 fix here, and adjust it follow Bernd's comment
add patch 3 which does right thing for shared mmap in FOPEN_DIRECT_IO mode
v1 -> v2:
make the new flag a fuse init one rather than a open flag since it's
not common that different files in a filesystem has different
strategy of shared mmap.
Hao Xu (3):
fuse: invalidate page cache pages before direct write
fuse: add a new fuse init flag to relax restrictions in no cache mode
fuse: write back dirty pages before direct write in direct_io_relax
mode

Hi Miklos,
Could you take a look at this one when you have time, since Bernd is
going to make his patch separate, this series is ready for reviewing.
Thanks,
Hao
