Hi Linus, As Ted mentioned the SMB case, in my understanding, we might have more users for in-kernel ut8 normalization/casefold comparison functions than just ext4 in the future. Steve French (in cc.), for instance, mentioned his interest in using this higher level NLS API when I first submitted these patches. My first RFC actually included this code as a separated module inside lib/ instead of touching NLS, but I found myself rewriting much of the same APIs that already existed in NLS. That is why I merged my work with that subsystem. I am open to rethinking it, if there is a better alternative. Thanks, -- Gabriel Krisman Bertazi
