From 60571c7d556b10db7e555bd4b6765647af5c41e8 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Thu, 2 Feb 2012 08:13:30 -0600 Subject: [PATCH] rbd: reduce memory used for rbd_dev fields The length of the string containing the monitor address specification(s) will never exceed the length of the string passed in to rbd_add(). The same holds true for the ceph + rbd options string. So reduce the amount of memory allocated for these to that length rather than the maximum (1024 bytes).
