Bug 693530 – sys-kernel/gentoo-sources-5.2.11 - mm/zsmalloc.c: In function ‘zs_create_pool’: mm/zsmalloc.c:2435:27: error: ‘struct zs_pool’ has no member named ‘migration_wait’

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Uladzimir Bely 2019-09-05 04:29:08 UTC]

gentoo-sources-5.2.1 fails to build, seems to be related with changes in upstream kernel.


Reproducible: Always

Steps to Reproduce:
emerge gento-sources:5.2.11
Actual Results:  
A piece of the build log:

Expected Results:  
Successfull build

The same kernel configuration was OK for all previous gento-sources-5.2.* versions.

[Comment 1 Uladzimir Bely 2019-09-05 05:07:15 UTC]

Build fails with CONFIG_ZSMALLOC only. If disabled in kernel config, build is OK.

[Comment 2 Mike Pagano 2019-09-05 18:53:35 UTC]

The fix is queued up in the upstream kernel repo. I would expect it to be in 5.1.12, but if not I will carry it for 5.1.12-gentoo-sources, myself.

[Comment 3 Mike Pagano 2019-09-20 23:15:06 UTC]

Released in kernel 5.2.12
