[Note: this mail contains only information for Linux kernel regression
tracking. Mails like these contain '#forregzbot' in the subject to make
then easy to spot and filter out. The author also tried to remove most
or all individuals from the list of recipients to spare them the hassle.]

Thanks for the report. To be sure below issue doesn't fall through the
cracks unnoticed, I'm adding it to regzbot, my Linux kernel regression
tracking bot:

#regzbot ^introduced e240e53ae0ab
#regzbot title mm, slub: CONFIG_SLUB_TINY causes various build errors
#regzbot ignore-activity

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.
