Subject: [PATCH v2 0/2] vfs: truncate bug fixes
Date: Thu, 22 Dec 2011 10:55:24 +0200 [thread overview]
Message-ID: <cover.1324543719.git.dmitry.kasatkin@intel.com> (raw)
When a file is opened with O_TRUNC or truncated with truncate()/ftruncate(),
and then closed, iversion is not updated. This patch uses ATTR_OPEN flag,
which is currently used to identify files opened with O_TRUNC,
as an indication to increment iversion.
Also it adds passing of this flag from do_sys_truncate and do_sys_ftruncate.
To reflect real meaning, ATTR_OPEN is suggested to be renamed to ATTR_TRUNC.
