Hi Andrew, After merging the akpm tree, today's linux-next build (arm multi_v7_defconfig) produced this warning: lib/lzo/lzo1x_compress.c: In function 'lzo1x_1_do_compress': lib/lzo/lzo1x_compress.c:239:14: warning: 'm_pos' may be used uninitialized in this function [-Wmaybe-uninitialized] m_off = ip - m_pos; ~~~^~~~~~~ Probably introduced by patch "lib/lzo: implement run-length encoding" or "lib/lzo: separate lzo-rle from lzo" -- Cheers, Stephen Rothwell
