From d1ccc4e400728d90f2ef7904661f53deb7199123 Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Wed, 8 May 2013 08:54:11 -0400 Subject: gluster: add fallocate fop support Implement support for the fallocate file operation. fallocate allocates blocks for a particular inode such that future writes to the associated region of the file are guaranteed not to fail with ENOSPC. This patch adds fallocate support to the following areas: - libglusterfs - mount/fuse - io-stats - performance/md-cache,open-behind - quota - cluster/afr,dht,stripe - rpc/xdr - protocol/client,server - io-threads - marker - storage/posix - libgfapi BUG: 949242 Change-Id: Ice8e61351f9d6115c5df68768bc844abbf0ce8bd Signed-off-by: Brian Foster Reviewed-on: http://review.gluster.org/4969 Tested-by: Gluster Build System Reviewed-by: Anand Avati --- rpc/xdr/src/glusterfs3-xdr.c | 40 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) (limited to 'rpc/xdr/src/glusterfs3-xdr.c') diff --git a/rpc/xdr/src/glusterfs3-xdr.c b/rpc/xdr/src/glusterfs3-xdr.c index a502b2ea16c..2ce0b84ede9 100644 --- a/rpc/xdr/src/glusterfs3-xdr.c +++ b/rpc/xdr/src/glusterfs3-xdr.c @@ -1506,6 +1506,46 @@ xdr_gfs3_fsetattr_rsp (XDR *xdrs, gfs3_fsetattr_rsp *objp) return TRUE; } +bool_t +xdr_gfs3_fallocate_req (XDR *xdrs, gfs3_fallocate_req *objp) +{ + register int32_t *buf; + buf = NULL; + + if (!xdr_opaque (xdrs, objp->gfid, 16)) + return FALSE; + if (!xdr_quad_t (xdrs, &objp->fd)) + return FALSE; + if (!xdr_u_int (xdrs, &objp->flags)) + return FALSE; + if (!xdr_u_quad_t (xdrs, &objp->offset)) + return FALSE; + if (!xdr_u_quad_t (xdrs, &objp->size)) + return FALSE; + if (!xdr_bytes (xdrs, (char **)&objp->xdata.xdata_val, (u_int *) &objp->xdata.xdata_len, ~0)) + return FALSE; + return TRUE; +} + +bool_t +xdr_gfs3_fallocate_rsp (XDR *xdrs, gfs3_fallocate_rsp *objp) +{ + register int32_t *buf; + buf = NULL; + + if (!xdr_int (xdrs, &objp->op_ret)) + return FALSE; + if (!xdr_int (xdrs, &objp->op_errno)) + return FALSE; + if (!xdr_gf_iatt (xdrs, &objp->statpre)) + return FALSE; + if (!xdr_gf_iatt (xdrs, &objp->statpost)) + return FALSE; + if (!xdr_bytes (xdrs, (char **)&objp->xdata.xdata_val, (u_int *) &objp->xdata.xdata_len, ~0)) + return FALSE; + return TRUE; +} + bool_t xdr_gfs3_rchecksum_req (XDR *xdrs, gfs3_rchecksum_req *objp) { -- cgit
