Subject[PATCH 4.4 046/241] fuse: honor RLIMIT_FSIZE in fuse_file_fallocate
Date
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.

Fixes: 05ba1f082300 ("fuse: add FALLOCATE operation")
Cc: <stable@vger.kernel.org> # v3.5
