From 24b35c3d97ffdbf0a1f8e8b4e94ed892343603a6 Mon Sep 17 00:00:00 2001
From: Miklos Szeredi <miklos@szeredi.hu>

Subject: * 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
