Subject: pagemap.h: Do not use hardcoded maximum number of kpageflags
X-Git-Url: http://git.itanic.dy.fi/?p=scan-pagemap;a=commitdiff_plain;h=a4261cff2ba98de4bb6bfd251092169a7fb4cf28

pagemap.h: Do not use hardcoded maximum number of kpageflags

The kpageflag definitions are subject to change. It is better to have
a dynamic maximum defined for this.

Furthermore, the previous maximum was actually wrong. The KSM pages
were never shown even if such pages were present on the system.
