- Intorduce and use a message type for VFS_GETDENTS, VFS_READ, VFS_WRITE. - Some cleanup to related functions where vir_bytes are replaced (and casted to/from, in parameter definition and local variables as well. This allow to see more clearly which function receives unsafe (pointer) values, or at least values which are not supposed to be valid in the address space of VFS. The current patch does so only for the minimal amount of functions which are concerned with the introduction of the new message type. Change-Id: I0cdca97409c4016d02fae067b48bf55d37572c5c
