Description

Setting HSM flags in

static int lfs_hsm_change_flags(int argc, char **argv, int mode)

does not allow to specify the archive_id, that is,

llapi_hsm_state_set(path, mask, 0, 0 /* archive_id */);

archive_id 0 is always set.

Add an optional parameter of the form:

usage: hsm_set [--norelease=<archive_id>] [--noarchive=<archive_id>] 
            [--dirty=<archive_id>] [--exists=<archive_id>]

for having full flexibility to specify the archive_id. If archive_id is not provided, then use default value archive_id=0. I will provided a simple patch for this problem
