mkdir, mknod) which will result in the server setting the
uid and gid to the default (usually the server uid of the
usern who mounted the share). Letting the server (rather than
user who mounted the share). Letting the server (rather than
the client) set the uid and gid is the default. This
parameter has no effect if the CIFS Unix Extensions are not
negotiated.

reads bigger than page size without rereading the same data)
this can provide better performance than the default

behavior which caches reads (readahead) and writes
(writebehind) through the local Linux client pagecache
