4507847c86
Support two generic fs ioctls FS_IOC_{GET,SET}FSLABEL, letting
f2fs pass generic/492 testcase.
Fixes were made by Eric where:
- f2fs: fix buffer overruns in FS_IOC_{GET, SET}FSLABEL
utf16s_to_utf8s() and utf8s_to_utf16s() take the number of characters,
not the number of bytes.
- f2fs: fix copying too many bytes in FS_IOC_SETFSLABEL
Userspace provides a null-terminated string, so don't assume that the
full FSLABEL_MAX bytes can always be copied.
- f2fs: add missing authorization check in FS_IOC_SETFSLABEL
FS_IOC_SETFSLABEL modifies the filesystem superblock, so it shouldn't be
allowed to regular users. Require CAP_SYS_ADMIN, like xfs and btrfs do.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
