[Bug 110674] Crashes / Resets From AMDGPU / Radeon VII

https://bugs.freedesktop.org/show_bug.cgi?id=110674 --- Comment #101 from ReddestDream --- Grasping at straws a bit here, but it occurred to me that maybe Linux kernel testing on Radeon VII was done on an early VBIOS that didn't have full UEFI support yet. We know that AMD had to issue a VBIOS

[PATCH] dma-buf: fix a memory leak bug

In sync_file_merge(), 'fences' is firstly allocated through kcalloc(). Later on, if the size is not sufficient, krealloc() is invoked to reallocate 'nfences', which is assigned to 'fences'. However, if krealloc() fails, 'fences' is not deallocated, leading to a memory leak bug. To fix the above
