Wong Refactor the SETFLAGS implementation to use the SETXATTR code directly instead of partially constructing a struct fsxattr and calling bits and pieces of the setxattr code. This reduces code size and becomes necessary in the next patch to maintain the behavior of allowing userspace to set immutable on an immutable file so long as nothing /else/ about the attributes change.
