On linux the request argument of ioctl() is defined as an unsigned long,
but the fuse protocol squashes it into a signed int. As a consequence
the value received by ntfs-3g may appear as negative and different from
the value defined by the corresponding macro.
So define the request argument as unsigned long in ntfs-3g. It has
however to be fed as unsigned from fuse until the fuse protocol is
updated.
This is backporting code from the full FUSE library in order to support
ioctls. The fuse protocol level negociated is now 7.18 instead of 7.8.
A fallback protocol to 7.8 is provided for compatibility with older kernels.
32-bit ioctls are not supported by a 64-bit library
When issuing an utimensat as a consequence of utime(2) or utimensat(2),
fuse had temporarily defined a flag utime_omit_ok to identify whether
the file system supports the values UTIME_OMIT and UTIME_NOW to mean
specific timestamp updatings. The flag has been obsoleted and all
file system are now supposed to comply with the convention.
The libfuse used by OpenIndiana has the same features as libfuse-lite
though requiring some code variants. Merging them simplifies supporting
both.
Variants for OpenIndiana are selected when defining __SOLARIS__
