Re: [PATCH 00/10] zram: various improvements and cleanups

[Anton Blanchard]

Hi Nitin,

I gave zram a try on a ppc64 box with a 64kB PAGE_SIZE. It looks like the
xvmalloc allocator fails when we add in a large enough block (in this case
65532 bytes).

flindex ends up as 127 which is larger than BITS_PER_LONG. We continually call
grow_block inside find_block and fail:

zram: Error allocating memory for compressed page: 0, size=467
