From 8bd0d701445ef263a52968ced2854c3d35712695 Mon Sep 17 00:00:00 2001 From: Ronnie Sahlberg Date: Fri, 17 Jan 2020 11:45:02 +1000 Subject: cifs: add support for fallocate mode 0 for non-sparse files RHBZ 1336264 When we extend a file we must also force the size to be updated. This fixes an issue with holetest in xfs-tests which performs the following sequence : 1, create a new file 2, use fallocate mode==0 to populate the file 3, mmap the file 4, touch each page by reading the mmapped region.
