From 0cbade024ba501313da3b7e5dd2a188a6bc491b5 Mon Sep 17 00:00:00 2001 From: Liu Bo Date: Thu, 18 Apr 2019 04:04:41 +0800 Subject: [PATCH] fuse: honor RLIMIT_FSIZE in fuse_file_fallocate fstests generic/228 reported this failure that fuse fallocate does not honor what 'ulimit -f' has set. This adds the necessary inode_newsize_ok() check.
