LZO_E_LOOKBEHIND_OVERRUN in latest zram #69

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Kernel 2.6.35.3
32bit HIGHMEM64
4gb of ram
6core amd

Latest zram will fail on decompression with LZO_E_LOOKBEHIND_OVERRUN (-6) and 
will never swapon (and sometimes fail on mkswap). Trying to remove the module 
will cause panic. 

The offending commit is 9b11aec2ea "Reduce per page table entry overhead by 4 
bytes" after bisection.

This change (and some others too) have been reverted and the code in the 
repository in now sync'ed with the mainline.  Can you please pull and try again?
