We re-introduce the functionality of invalidating the caches for an
inode specified by path by adding a new routine
fuse_invalidate_path. This is useful for network-based file systems
which use the high-level API, enabling them to notify the kernel about
external changes.
This is a revival of Miklos Szeredi's original code for the
fuse_invalidate routine.
This reverts commit d5cdbb94a0.
null works completely fine, just the mountpoint should
be a regular file -- so there is no need to dismiss it.
Also:
- fixing up compiler warnings
- checking if the mountpoint is a regular file
An earlier version of the fioclient.c example was intended to be
used together with cusexmp.c. The former has since evolved into
ioctl_client.c and no longer has the function necessary to test
CUSE. Therefore, we've added a new cuse_client.c that is clearly
associated with the cuse.c example file system.
