I was intrigued and looked for details. Thankfully though, nowadays many virtual files in /proc are generated via `single_open_size`, which is a simpler version of `seq_file` which has no such problem (to my best understanding) because it should generate the whole file contents in one go. I couldn't pinpoint the exact kernel version though, the transition seems to have happened somewhere in the 3.1x era.
