This will set memcg_data of the old folio to 0. Similarly, if migration failed, memcg_data of the dst folio is left unset. If we call folio_putback_lru() on such folios (memcg_data == 0), we will add the folio to be freed to the LRU, making memcg code unhappy.

This will call the net_dm_monitor_start() function that uses a spinlock that has not yet been initialized. To fix this, let's place resource initialization above the registration of a generic netlink family. Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org) with Syzkaller.

[PATCH] agp: Fix a potential memory leak bug in agp_amdk7_probe()

by Haoxiang Li

Variable "bridge" is allocated by agp_alloc_bridge() and have to be released by agp_put_bridge() if something goes wrong. In this patch, add the missing call of agp_put_bridge() in agp_amdk7_probe() to prevent potential memory leak bug.

Re: REGRESSION amdgpu 20241108 firmware breaks screen updating

by mail＠tteles.dev

I can confirm amdgpu.dcdebugmask=0x200 fixes it, no more stutters. It would be very beneficial to include the patch making this behavior default (https://lore.kernel.org/amd-gfx/20250221160145.1730752-3-zaeem.mohamed@amd.…) in the relevant linux-stable trees, as this is a major issue for affected systems. I CC'd stable(a)vger.kernel.org and ask for the patch to be included in linux-stable, even though it does not have a "Fixes:" tag, if the maintainers are okay with it.
