From 752c8bdcfe88f27a17c5c9264df928fd145a4b30 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Tue, 5 Feb 2013 13:52:29 -0800 Subject: [PATCH] ceph: do not chain inode updates to parent fsync The fsync(dirfd) only covers namespace operations, not inode updates. We do not need to cover setattr variants or O_TRUNC.
