in_interrupt() check in memcg_kmem_bypass() is incorrect because it does not allow to account memory allocation called from task context with disabled BH, i.e. inside spin_lock_bh()/spin_unlock_bh() sections Signed-off-by: Vasily Averin <redacted>In that file in_interrupt() is used at other places too. Should we change those too?Yes, it seems so. Let me prepare a fix (it seems like most of them were introduced by me).
No objects from my side, just keep me informed and add me in "Reported-by:" in your patches. Thank you, Vasily Averin
