Update of /cvsroot/linuxcompressed/linux/include/linux
In directory usw-pr-cvs1:/tmp/cvs-serv2127/include/linux
Modified Files:
comp_cache.h swap.h
Log Message:
- In 2.4.10 the MAX_SWAPFILES was changed, what caused some problems for our
code in architectures like UML, which handles swap entry addresses
differently than in i386. That way, we cannot keep using MAX_SWAPFILES for
our swap type unless we decrease this variable. In this case, we decreased
the variable to 31 and so we can use 31 as COMP_CACHE_SWP_TYPE without
worrying about arch-dependent configuration. Nevertheless, we are limited to
31 swap files, not 32 as in vanilla.
