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 --- xlators/protocol/client/src/client.c | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) (limited to 'xlators/protocol/client/src/client.c') diff --git a/xlators/protocol/client/src/client.c b/xlators/protocol/client/src/client.c index e24282e285e..377263af64a 100644 --- a/xlators/protocol/client/src/client.c +++ b/xlators/protocol/client/src/client.c @@ -1961,6 +1961,40 @@ out: return 0; } +int32_t +client_fallocate(call_frame_t *frame, xlator_t *this, fd_t *fd, int32_t mode, + off_t offset, size_t len, dict_t *xdata) +{ + int ret = -1; + clnt_conf_t *conf = NULL; + rpc_clnt_procedure_t *proc = NULL; + clnt_args_t args = {0,}; + + conf = this->private; + if (!conf || !conf->fops) + goto out; + + args.fd = fd; + args.flags = mode; + args.offset = offset; + args.size = len; + args.xdata = xdata; + + proc = &conf->fops->proctable[GF_FOP_FALLOCATE]; + if (!proc) { + gf_log (this->name, GF_LOG_ERROR, + "rpc procedure not found for %s", + gf_fop_list[GF_FOP_FALLOCATE]); + goto out; + } + if (proc->fn) + ret = proc->fn (frame, this, &args); +out: + if (ret) + STACK_UNWIND_STRICT (fallocate, frame, -1, ENOTCONN, NULL, NULL, NULL); + + return 0; +} int32_t client_getspec (call_frame_t *frame, xlator_t *this, const char *key, @@ -2679,6 +2713,7 @@ struct xlator_fops fops = { .fxattrop = client_fxattrop, .setattr = client_setattr, .fsetattr = client_fsetattr, + .fallocate = client_fallocate, .getspec = client_getspec, }; -- cgit
