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/performance/open-behind/src/open-behind.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'xlators/performance/open-behind') diff --git a/xlators/performance/open-behind/src/open-behind.c b/xlators/performance/open-behind/src/open-behind.c index b405b94cd54..5ac813132eb 100644 --- a/xlators/performance/open-behind/src/open-behind.c +++ b/xlators/performance/open-behind/src/open-behind.c @@ -681,6 +681,24 @@ err: return 0; } +int +ob_fallocate(call_frame_t *frame, xlator_t *this, fd_t *fd, int32_t mode, + off_t offset, size_t len, dict_t *xdata) +{ + call_stub_t *stub; + + stub = fop_fallocate_stub(frame, default_fallocate_resume, fd, mode, + offset, len, xdata); + if (!stub) + goto err; + + open_and_resume(this, fd, stub); + + return 0; +err: + STACK_UNWIND_STRICT(fallocate, frame, -1, ENOMEM, NULL, NULL, NULL); + return 0; +} int ob_unlink (call_frame_t *frame, xlator_t *this, loc_t *loc, int xflags, @@ -903,6 +921,7 @@ struct xlator_fops fops = { .fentrylk = ob_fentrylk, .fxattrop = ob_fxattrop, .fsetattr = ob_fsetattr, + .fallocate = ob_fallocate, .unlink = ob_unlink, .rename = ob_rename, .lk = ob_lk, -- cgit
