[PATCH] md, sysfs, LLVMLinux: Remove nested function from bcache sysfs
Replace the use of nested functions where a normal function will suffice.
Nested functions are not liked by upstream kernel developers in general. Their
use breaks the use of clang as a compiler, and doesn't make the code any
better.
This code now works for both gcc and clang.
