I think I was very confused at what this patch does, and what it does seems confused as well. The patch adds a new flag to the STATX_ATTR_* namespace, which historically was used for persistent on-disk flags like immutable, not the STATX_* namespace where I assumed it, and which has no support mask. Which seems really odd for a pure kernel feature. Then again it seems to follow STATX_ATTR_WRITE_ATOMIC which seems just as wrongly place unless I'm missing something?
