From: Zhu Lingshan Date: Wed, 1 Jul 2026 08:08:12 +0000 (+0800) Subject: amdkfd: properly free secondary context id X-Git-Tag: v7.2-rc3~27^2~2^2~3 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a88419af8dbd5abf8b1dfdfd9346376bce5413b4;p=thirdparty%2Fkernel%2Flinux.git amdkfd: properly free secondary context id Function kfd_process_free_id() should skip over the primary kfd process because its context id is fixed assigned, not allocated through the ida table. This function should only work on secondary contexts.
