Date: Thu, 25 Sep 2014 16:05:22 +0400 From: Maxim Patlasov <MPatlasov@...allels.com> To: miklos@...redi.hu Cc: fuse-devel@...ts.sourceforge.net, avati@...ster.org, linux-kernel@...r.kernel.org Subject: [PATCH 1/5] fuse: add FOPEN_SYNC_RELEASE flag to ff->open_flags The feature will be governed by fuse file open flag FOPEN_SYNC_RELEASE. Userspace can enable it on per file basis in the same way as for FOPEN_KEEP_CACHE or FOPEN_DIRECT_IO.
