Re: [libvirt] [PATCH v2 1/9] virstoragefile: Add virStorageSourceGetBackingStore

Create virStorageSourceGetBackingStore function in preparation for quorum: Actually, if we want to get a backing store inside a virStorageSource we have to do it manually(src->backingStore = backingStore). The problem is that with a quorum, a virStorageSource can contain multiple backing stores, and src->backingStore can be treated as a virStorageSourcePtr or a virStorageSourcePtrPtr. Due to these reason, we need to simplify the manipulation of virStorageSource, and create a function to get the asked backingStore in a virStorageSource For now, this function only return the backingStore field Signed-off-by: Matthias Gatto <matthias.gatto(a)outscale.com&gt; --- src/libvirt_private.syms | 1 + src/util/virstoragefile.c | 8 ++++++++ src/util/virstoragefile.h | 3 +++ 3 files changed, 12 insertions(+) diff --git a/src/libvirt_private.syms b/src/libvirt_private.syms index a2eec83..3f4d02c 100644 --- a/src/libvirt_private.syms +++ b/src/libvirt_private.syms @@ -2023,6 +2023,7 @@ virStorageSourceClear; virStorageSourceCopy; virStorageSourceFree; virStorageSourceGetActualType; +virStorageSourceGetBackingStore; virStorageSourceGetSecurityLabelDef; virStorageSourceInitChainElement; virStorageSourceIsEmpty; diff --git a/src/util/virstoragefile.c b/src/util/virstoragefile.c index 7a4f9a0..dc6cf8f 100644 --- a/src/util/virstoragefile.c +++ b/src/util/virstoragefile.c @@ -1798,6 +1798,14 @@ virStorageSourcePoolDefCopy(const virStorageSourcePoolDef *src) } +virStorageSourcePtr +virStorageSourceGetBackingStore(const virStorageSource *src, + size_t pos ATTRIBUTE_UNUSED) +{ + return src->backingStore; +} + + /** * virStorageSourcePtr: * diff --git a/src/util/virstoragefile.h b/src/util/virstoragefile.h index b4c3808..c37ddcf 100644 --- a/src/util/virstoragefile.h +++ b/src/util/virstoragefile.h @@ -289,6 +289,9 @@ struct _virStorageSource { # define DEV_BSIZE 512 # endif +virStorageSourcePtr virStorageSourceGetBackingStore(const virStorageSource *src, + size_t pos); + int virStorageFileProbeFormat(const char *path, uid_t uid, gid_t gid); int virStorageFileProbeFormatFromBuf(const char *path, char *buf,
