Subject: [PATCH 2/4] fs: Prevent doing FALLOC_FL_ZERO_RANGE on append only file
Date: Fri, 11 Apr 2014 20:57:43 +0200 [thread overview]
Message-ID: <1397242665-2183-2-git-send-email-lczerner@redhat.com> (raw)
In-Reply-To: <1397242665-2183-1-git-send-email-lczerner@redhat.com>
Currently punch hole and collapse range fallocate operation are not
allowed on append only file. This should be case for zero range as well.
Fix it.
