From 009dd694e82098a703b8b5c8dd9f54c131dbb9b3 Mon Sep 17 00:00:00 2001 From: Maxim Patlasov Date: Mon, 28 Apr 2014 14:19:22 +0200 Subject: [PATCH] fuse: update mtime on truncate(2) Handling truncate(2), VFS doesn't set ATTR_MTIME bit in iattr structure; only ATTR_SIZE bit is set. In-kernel fuse must handle the case by setting mtime fields of struct fuse_setattr_in to "now" and set FATTR_MTIME bit even though ATTR_MTIME was not set.
