From: Ilya Dryomov idryomov@gmail.com Subject: mm/oom: fix pgtables units mismatch in Killed process message

pr_err() expects kB, but mm_pgtables_bytes() returns the number of bytes. As everything else is printed in kB, I chose to fix the value rather than the string.

Before:

[ pid ] uid tgid total_vm rss pgtables_bytes swapents oom_score_adj name ... [ 1878] 1000 1878 217253 151144 1269760 0 0 python ... Out of memory: Killed process 1878 (python) total-vm:869012kB, anon-rss:604572kB, file-rss:4kB, shmem-rss:0kB, UID:1000 pgtables:1269760kB oom_score_adj:0

After:

[ pid ] uid tgid total_vm rss pgtables_bytes swapents oom_score_adj name ... [ 1436] 1000 1436 217253 151890 1294336 0 0 python ... Out of memory: Killed process 1436 (python) total-vm:869012kB, anon-rss:607516kB, file-rss:44kB, shmem-rss:0kB, UID:1000 pgtables:1264kB oom_score_adj:0
