fs/proc/base.c: fix proc_fault_inject_write() input sanity check
Remove obfuscated zero-length input check and return -EINVAL instead of -EIO error to make the error message clear to user. Add whitespace stripping. No functionality changes. The old code: echo 1 > /proc/pid/make-it-fail (ok) echo 1foo > /proc/pid/make-it-fail (-bash: echo: write error: Input/output error) The new code: echo 1 > /proc/pid/make-it-fail (ok) echo 1foo > /proc/pid/make-it-fail (-bash: echo: write error: Invalid argument) This patch is conservative in changes to not breaking existing scripts/applications.
