After that, an example is, in 'servers' tuple values we use 'server' variable for key 'host' in the code, it will be quite messy to have colliding names for variables, so to maintain better readability and makes it consistent with other existing code as well as the input keys/options, this patch renames the following variables 'server' -> 'host' 'image' -> 'path' 'volname' -> 'volume' Signed-off-by: Prasanna Kumar Kalever Reviewed-by: Eric Blake --- block/gluster.c | 54 +++++++++++++++++++++++++++--------------------------- 1 file changed, 27 insertions(+), 27 deletions(-) diff --git a/block/gluster.c b/block/gluster.c index 1eb3a8c..513a774 100644 --- a/block/gluster.c +++ b/block/gluster.c @@ -25,19 +25,19 @@ typedef struct BDRVGlusterState { } BDRVGlusterState; typedef struct GlusterConf { - char *server; + char *host; int port; - char *volname; - char *image; + char *volume; + char *path; char *transport; } 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); } @@ -57,19 +57,19 @@ 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. * @@ -78,10 +78,10 @@ static int parse_volume_options(GlusterConf *gconf, char *path) * tcp, unix and rdma.
