Hi Greg,
Please include this patch and the following one for sysfs. This is needed
after the introduction of sysfs setattr functionality.
Thanks
Maneesh
o sysfs_chmod_file() must update the new iattr field in sysfs_dirent else
the mode change will not be persistent in case of inode evacuation from
cache.
