* The context is extended with a 'umask' field. The umask is sent
for mknod, mkdir and create requests by linux kernel version
2.6.31 or later, otherwise the umask is set to zero. Also
introduce a new feature flag: FUSE_CAP_DONT_MASK. If the kernel
supports this feature, then this flag will be set in conn->capable
in the ->init() method. If the filesystem sets this flag in in
conn->want, then the create modes will not be masked.
* Add low level interfaces for lookup cache and attribute
invalidation. This feature is available in linux kernels 2.6.31
or later. Patch by John Muir
* Kernel interface version is now 7.12
