From 6df6f801f879a690e9ff61fa04c2551babb5d73a Mon Sep 17 00:00:00 2001 From: Prasanna Kumar Kalever Date: Fri, 22 Jul 2016 19:22:05 +0200 Subject: [PATCH 01/10] block/gluster: rename [server, volname, image] -> [host, volume, path] RH-Author: Prasanna Kumar Kalever Message-id: <1469215330-14515-2-git-send-email-prasanna.kalever@redhat.com> Patchwork-id: 71336 O-Subject: [RHEV-7.3 qemu-kvm-rhev PATCH v2 1/6] block/gluster: rename [server, volname, image] -> [host, volume, path] Bugzilla: 1247933 RH-Acked-by: Jeffrey Cody RH-Acked-by: Stefan Hajnoczi RH-Acked-by: Markus Armbruster A future patch will add support for multiple gluster servers. 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 Message-id: 1468947453-5433-2-git-send-email-prasanna.kalever@redhat.com Signed-off-by: Jeff Cody (cherry picked from commit d5cf4079ca713cccd16302159fc06f8540c33a57) Signed-off-by: Prasanna Kumar Kalever Signed-off-by: Miroslav Rezanina --- block/gluster.c | 54 +++++++++++++++++++++++++++--------------------------- 1 file changed, 27 insertions(+), 27 deletions(-) diff --git a/block/gluster.c b/block/gluster.c index f611074..0b9a861 100644 --- a/block/gluster.c +++ b/block/gluster.c @@ -28,10 +28,10 @@ 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; @@ -39,9 +39,9 @@ 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); } @@ -61,19 +61,19 @@ 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. * @@ -82,10 +82,10 @@ static int parse_volume_options(GlusterConf *gconf, char *path) * tcp, unix and rdma.
