Biederman" <ebiederm@...ssion.com> Subject: [PATCH 4.1 100/102] fs: Set the size of empty dirs to 0. 4.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: "Eric W. Biederman" <ebiederm@...ssion.com> commit 4b75de8615050c1b0dd8d7794838c42f74ed36ba upstream. Before the make_empty_dir_inode calls were introduce into proc, sysfs, and sysctl those directories when stated reported an i_size of 0. make_empty_dir_inode started reporting an i_size of 2. At least one userspace application depended on stat returning i_size of 0. So modify make_empty_dir_inode to cause an i_size of 0 to be reported for these directories.
