https://bugzilla.kernel.org/show_bug.cgi?id=151491 --- Comment #11 from Betacentauri (betacentauri@xxxxxxxx) --- nodelalloc mount options workarounds the problem in the test environment. But I also checked with real ARM system with 4.1.37 kernel: root@sf4008:/media# mount ... /dev/sda on /media/sda type ext4 (rw,relatime,nodelalloc,data=ordered) root@sf4008:/media# ls -las sda/testfiles/ 10240 -rw-r--r-- 1 root root 10485760 Nov 17 16:47 test 10304 -rw-r--r-- 1 root root 10485760 Nov 17 16:47 test1 Test is a little bit different. Only 10 MB files are generated. In most cases file size (first column) is equal, but in some cases file size still differs like in above example. It's not deterministic for me when it happens. But I only see 2 sizes. 10240 or 10304. With delalloc the file size was much more random. -- You are receiving this mail because: You are watching the assignee of the bug.
