Subject: swapon: use unmangle() for filenames from /proc/swaps
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bf71ef0797c42f4b1754ec8756819c633a0d0d73;p=util-linux

swapon: use unmangle() for filenames from /proc/swaps

linux kernel encodes all garbage in filenames by mangle() function. We
need to unmagle() to get the real filenames.
