| H A D | decompress_unlz4.c | diff 4d4b866aee039d609c0b40e7e5b27204607ce614 Fri Aug 08 23:23:10 CEST 2014 Yinghai Lu <yinghai@kernel.org> initrd: fix lz4 decompress with initrd
During testing initrd (>2G) support, find decompress/lz4 does not work
with initrd at all.
decompress_* should support:
1. inbuf[]/outbuf[] for kernel preboot.
2. inbuf[]/flush() for initramfs
3. fill()/flush() for initrd.
in the unlz4 does not handle case 3, as input len is passed as 0, and it
failed in first try.
Fix that add one extra if (fill) checking, and get out if EOF from the
fill().
