Cannot mount overlay fs with long lowerdir paths

[Vladimir Smelhaus <vl.sm@xxxxxxxx>]

Hello,

mounting overlay fs doesn't work if the command line with referenced lowerdir paths is longer than "something". The change occurred somewhere between versions 2.38.1 and 2.40.1. Tested on Debian with kernel 6.7.12 and 6.8.9, kernel version has no effect. I 
never encountered any limit before, until now.
