This was done to allow usersapce the opportunity to transition slowly from a 32b address space, and to avoid breaking inherent 32b assumptions of some commands. However, for insert we limited ourselves to 4G-4K, but on verification we allowed the full 4G. This causes some attempts to bind a new buffer to sporadically fail with -ENOSPC, but at other times be bound successfully. commit 48ea1e32c39d ("drm/i915/gen9: Set PIN_ZONE_4G end to 4GB - 1 page") suggests that there is a genuine problem with stateless addressing that cannot utilize the last page in 4G and so we purposefully excluded it. This means that the quick pin pass may cause us to utilize a buggy placement.

[stable] ext4 fscrypt_get_encryption_info() circular locking dependency

by Sergey Senozhatsky

Hi, I got the following lockdep splat the other day, while running some tests on 4.19. I didn't test other stable kernels, but it seems that 5.4 should also have similar problem.
