I am looking at scheduling flags in linux/sched.h, and I am unsure of the
meaning of this one:
#define PF_BORROWED_MM 0x00400000 /* I am a kthread doing use_mm */
What exactly is a kthread, and what does it mean to "use_mm"?
Would it be reasonable for a cyrus imapd process to ever have this flag set?
Thanks,
Michael
