1. the recent filehandle changes reduced opaqueness of filehandles.
ie. syscalls now determine the size of handles from fid_len.
how about adding an explicit size argument to fhopen and friends instead,
so that we can keep filehandles opaque and we don't need to have
an ugly copyin-twice hack in kernel?
2. how about unexporting fhandle_t from userland completely?
ie. make them void *. as filehandle is now variable sized,
there isn't much point to represent it as a C structure.
(this can be done without abi change.)
int getfh(const char *path, void *fhp, size_t *size);
int fhopen(const void *fhp, size_t size, int flags);
