[lc-checkins] CVS: linux/include/linux comp_cache.h,1.62,1.63

[Rodrigo S. de C. <rc...@us...>]

Update of /cvsroot/linuxcompressed/linux/include/linux
In directory usw-pr-cvs1:/tmp/cvs-serv24950/include/linux

Modified Files:
	comp_cache.h 
Log Message:
- Fixed a bug reported by Paolo Ciarrocchi (kernel BUG at vswap.c:380). The
cause of this bug is the variable used for offset in vswap_address. It had
been declared as unsigned short, so if we had more than 32767 entries in
vswap address table, the offset field of a entry with a higher offset would
report the wrong offset, causing corruption (including the one Paolo had).
To fix it, offset field hass been changed to unsigned long. Also all the
variables used to index when creating or resizing vswap were changed to
unsigned long as well.
