Subject: GFS2: O_TRUNC not working on stuffed files across cluster
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a8bf2bc212e129dd59a8b06cdbc15079cc3bd876;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

GFS2: O_TRUNC not working on stuffed files across cluster

This patch replaces a statement that got dropped out by accident.
Without the patch, truncates on stuffed (very small) files cause
those files to have an unpredictable size.
