Hi,
I would like to know if I can use kmap_atomic with KM_USER[01] type within a non-interrupt context. Looking at comments near kmap_atomic declarations on sparc or ppc, it seems that this is discouraged.
But lots of code (like filesystem stuff) are currently using it outside of interrupt context. Are there special requirements about KM_USER[01] usage in interrupt or non-interrupt contexts ? Is it documented somewhere how we can use it ?
What I want to do is just kmap_atomic, copy and kunmap_atomic.
