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.x | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) (limited to 'rpc/xdr/src/glusterfs3-xdr.x') diff --git a/rpc/xdr/src/glusterfs3-xdr.x b/rpc/xdr/src/glusterfs3-xdr.x index 063f302d9..7fad58336 100644 --- a/rpc/xdr/src/glusterfs3-xdr.x +++ b/rpc/xdr/src/glusterfs3-xdr.x @@ -566,6 +566,23 @@ struct gfs3_fstat_req { opaque xdata<>; /* Extra data */ } ; + struct gfs3_fallocate_req { + opaque gfid[16]; + hyper fd; + unsigned int flags; + unsigned hyper offset; + unsigned hyper size; + opaque xdata<>; /* Extra data */ +} ; + + struct gfs3_fallocate_rsp { + int op_ret; + int op_errno; + struct gf_iatt statpre; + struct gf_iatt statpost; + opaque xdata<>; /* Extra data */ +} ; + struct gfs3_rchecksum_req { hyper fd; unsigned hyper offset; -- cgit
