From f66f8b94e7f2f4ac9fffe710be231ca8f25c5057 Mon Sep 17 00:00:00 2001 From: Ronnie Sahlberg Date: Wed, 1 Jun 2022 08:48:38 +1000 Subject: [PATCH] cifs: when extending a file with falloc we should make files not-sparse as this is the only way to make sure the region is allocated. Fix the conditional that was wrong and only tried to make already non-sparse files non-sparse.
