Hi, Al,
commit 22dc9a1682722fda8603991595528b87e90436f6
Author: Al Viro <viro@zeniv.linux.org.uk>
Date: Thu Jun 28 15:53:17 2018 -0400
new primitive: discard_new_inode()
from current linux-next introduces the following problem.
It reproduces 100% in my test VM:
# cat /etc/mtab
/dev/sda1 / ext4 rw 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
devpts /dev/pts devpts rw,gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs rw,noexec,nosuid,nodev 0 0
# echo 3 > /proc/sys/vm/drop_caches
# cat /etc/mtab
cat: /etc/mtab: Cannot allocate memory
Though:
# free
total used free shared buffers cached
Mem: 4047432 99988 3947444 0 1340 49148
