Subject: [PATCH v3 3/5] Documentation/ABI: mark old kexec sysfs deprecated
Date: Mon, 10 Nov 2025 10:01:41 +0530	[thread overview]
Message-ID: <20251110043143.484408-4-sourabhjain@linux.ibm.com> (raw)
In-Reply-To: <20251110043143.484408-1-sourabhjain@linux.ibm.com>

The previous commit ("kexec: move sysfs entries to /sys/kernel/kexec")
moved all existing kexec sysfs entries to a new location. The ABI
document is updated to include a note about the deprecation of the old
kexec sysfs entries.

The following kexec sysfs entries are deprecated:
- /sys/kernel/kexec_loaded
- /sys/kernel/kexec_crash_loaded
- /sys/kernel/kexec_crash_size
- /sys/kernel/crash_elfcorehdr_size
