Subject: [PATCH v1 2/2] kexec_core: Drop redundant pm_restore_gfp_mask() call
Date: Thu, 10 Jul 2025 15:12:20 +0200 [thread overview]
Message-ID: <1949230.tdWV9SEqCh@rjwysocki.net> (raw)
In-Reply-To: <5046396.31r3eYUQgx@rjwysocki.net>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Drop the direct pm_restore_gfp_mask() call from the KEXEC_JUMP flow in
kernel_kexec() because it is redundant. Namely, dpm_resume_end()
called beforehand in the same code path invokes that function and
it is sufficient to invoke it once.
