It is an encoding library, it doesn't care about dentries, nor should know how to handle them. It exposes a simple api to manipulate and convert utf8 strings. I saw change was after the desire to not have these functions polluting the VFS hot path, but that has nothing to do with placing them here. Would libfs be better? or a casefolding library in fs/casefold.c? -- Gabriel Krisman Bertazi ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/
