sysfs-iattr: add sysfs_setattr
PATCH 2/3 sysfs-iattr: add sysfs_setattr
o This adds ->i_op->setattr VFS method for sysfs inodes. The changed attribues are saved in the persistent sysfs_dirent structure as a pointer to struct iattr. The struct iattr is allocated only for those sysfs_dirent's for which default attributes are getting changed. Thanks to Jon Smirl for this suggestion.
