Hi, I replied to v5 after the bot reports:
Sorry, my suggestion (to reuse mem_lseek() from proc) was wrong as the
kernel test bot just showed us. mem_lseek() may be unavailable without
CONFIG_PROC_FS.
The easiest way is to add a page_owner specific lseek function back as in
the early version, but make it correct for SEEK_CUR. Thanks.
