Revision 5ef50c3bec20060bc114f62d6503c5d86d70bdd7 authored by Sage Weil on 31 July 2012, 18:27:36 UTC, committed by Sage Weil on 02 August 2012, 16:11:19 UTC
The initial ->atomic_open op was carried over from the old intent code, which was incomplete and didn't really work. Replace it with a fresh method. In particular: * always attempt to do an atomic open+lookup, both for the create case and for lookups of existing files. * fix symlink handling by returning 1 to the VFS so that we can follow the link to its destination. This fixes a longstanding ceph bug (#2392). Signed-off-by: Sage Weil <sage@inktank.com>
