| Subject: fuse: honor RLIMIT_FSIZE in fuse_file_fallocate |
| |
| From: Liu Bo <bo.liu@linux.alibaba.com> |
| |
| commit 0cbade024ba501313da3b7e5dd2a188a6bc491b5 upstream. |
| |
| 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. |
