Vitaly Mayatskikh 0816178638 pagemap: require aligned-length, non-null reads of /proc/pid/pagemap ... The intention of commit aae8679b0e ("pagemap: fix bug in add_to_pagemap, require aligned-length reads of /proc/pid/pagemap") was to force reads of /proc/pid/pagemap to be a multiple of 8 bytes, but now it allows to read 0 bytes, which actually puts some data to user's buffer. According to POSIX, if count is zero, read() should return zero and has no other results.
