Subject[PATCH v2] let kernfs_name_locked & kernfs_name return size_t
Date
Simple patch that changes the return value of kernfs_name_locked and kernfs_name
to size_t which alignes these functions with kernfs_path_len which also returns
size_t.

Patch was made against for-4.5 branch of Tejun's cgroup tree. (As per Tejun's
request, ccing gregkh@linuxfoundation.org and linux-kernel@vger.kernel.org.)

Changelog
20150210: - Change return type of kernfs_name in kernfs.h as well.
- Build tested against Tejun's for-4.5 tree, 4.5-rc2 and
mainline 4.5-rc3.

*Note*, the changes in kernfs.h change the dummy return value of the static
inline definition of kernfs_name from -ENOSYS. I changed it to 0 analogous to
kernfs_path_len. I don't know if this is considered a deal-breaker.
