This callback +has changed its arguments, pre- and post-stat structures have been +added. This makes it possible to improve caching, which is useful for +Samba and NFS-Ganesha, but not so much for QEMU. Gluster 6 is the first +release that includes these new arguments. + +With an additional detection in ./configure, the new arguments can +conditionally get included in the glfs_io_cbk handler. + +Signed-off-by: Niels de Vos <ndevos@redhat.com> +Signed-off-by: Kevin Wolf <kwolf@redhat.com> +--- + block/gluster.c | 6 +++++- + configure | 24 ++++++++++++++++++++++++ + 2 files changed, 29 insertions(+), 1 deletion(-) + +diff --git a/block/gluster.c b/block/gluster.c +index f853aa8..51f184c 100644 +--- a/block/gluster.c ++++ b/block/gluster.c +@@ -729,7 +729,11 @@ static struct glfs *qemu_gluster_init(BlockdevOptionsGluster *gconf, + /* + * AIO callback routine called from GlusterFS thread. + */ +-static void gluster_finish_aiocb(struct glfs_fd *fd, ssize_t ret, void *arg) ++static void gluster_finish_aiocb(struct glfs_fd *fd, ssize_t ret, ++#ifdef CONFIG_GLUSTERFS_IOCB_HAS_STAT ++ struct glfs_stat *pre, struct glfs_stat *post, ++#endif ++ void *arg) + { + GlusterAIOCB *acb = (GlusterAIOCB *)arg; + +diff --git a/configure b/configure +index 5354d51..45a3654 100755 +--- a/configure ++++ b/configure +@@ -457,6 +457,7 @@ glusterfs_discard="no" + glusterfs_fallocate="no" + glusterfs_zerofill="no" + glusterfs_ftruncate_has_stat="no" ++glusterfs_iocb_has_stat="no" + gtk="" + gtk_gl="no" + tls_priority="NORMAL" +@@ -4105,6 +4106,25 @@ EOF + if compile_prog "$glusterfs_cflags" "$glusterfs_libs" ; then + glusterfs_ftruncate_has_stat="yes" + fi ++ cat > $TMPC << EOF ++#include <glusterfs/api/glfs.h> ++ ++/* new glfs_io_cbk() passes two additional glfs_stat structs */ ++static void ++glusterfs_iocb(glfs_fd_t *fd, ssize_t ret, struct glfs_stat *prestat, struct glfs_stat *poststat, void *data) ++{} ++ ++int ++main(void) ++{ ++ glfs_io_cbk iocb = &glusterfs_iocb; ++ iocb(NULL, 0 , NULL, NULL, NULL); ++ return 0; ++} ++EOF ++ if compile_prog "$glusterfs_cflags" "$glusterfs_libs" ; then ++ glusterfs_iocb_has_stat="yes" ++ fi + else + if test "$glusterfs" = "yes" ; then + feature_not_found "GlusterFS backend support" \ +@@ -6994,6 +7014,10 @@ if test "$glusterfs_ftruncate_has_stat" = "yes" ; then + echo "CONFIG_GLUSTERFS_FTRUNCATE_HAS_STAT=y" >> $config_host_mak + fi + ++if test "$glusterfs_iocb_has_stat" = "yes" ; then ++ echo "CONFIG_GLUSTERFS_IOCB_HAS_STAT=y" >> $config_host_mak ++fi ++ + if test "$libssh2" = "yes" ; then + echo "CONFIG_LIBSSH2=m" >> $config_host_mak + echo "LIBSSH2_CFLAGS=$libssh2_cflags" >> $config_host_mak +-- +1.8.3.1 + |
