Existing terminology is a bit unusual in relation to what names are used by other networked devices, and doesn't map very well to the terminology we expect to use for multiple servers. Therefore, rename the following options: 'server' -> 'host' 'image' -> 'path' 'volname' -> 'volume' Signed-off-by: Prasanna Kumar Kalever Reviewed-by: Eric Blake Reviewed-by: Jeff Cody --- block/gluster.c | 54 +++++++++++++++++++++++++++--------------------------- 1 file changed, 27 insertions(+), 27 deletions(-) diff --git a/block/gluster.c b/block/gluster.c index 16f7778..f1ac9a2 100644 --- a/block/gluster.c +++ b/block/gluster.c @@ -29,10 +29,10 @@ typedef struct BDRVGlusterState { } BDRVGlusterState; typedef struct GlusterConf { - char *server; + char *host; int port; - char *volname; - char *image; + char *volume; + char *path; char *transport; int debug_level; } GlusterConf; @@ -40,9 +40,9 @@ typedef struct GlusterConf { static void qemu_gluster_gconf_free(GlusterConf *gconf) { if (gconf) { - g_free(gconf->server); - g_free(gconf->volname); - g_free(gconf->image); + g_free(gconf->host); + g_free(gconf->volume); + g_free(gconf->path); g_free(gconf->transport); g_free(gconf); } @@ -62,19 +62,19 @@ static int parse_volume_options(GlusterConf *gconf, char *path) if (*p == '\0') { return -EINVAL; } - gconf->volname = g_strndup(q, p - q); + gconf->volume = g_strndup(q, p - q); - /* image */ + /* path */ p += strspn(p, "/"); if (*p == '\0') { return -EINVAL; } - gconf->image = g_strdup(p); + gconf->path = g_strdup(p); return 0; } /* - * file=gluster[+transport]://[server[:port]]/volname/image[?socket=...] + * file=gluster[+transport]://[host[:port]]/volume/path[?socket=...] * * 'gluster' is the protocol. * @@ -83,10 +83,10 @@ static int parse_volume_options(GlusterConf *gconf, char *path) * tcp, unix and rdma.
