Subject: [PATCH v3 2/7] crash: remove an unused argument from reserve_crashkernel_generic()
Date: Fri, 31 Jan 2025 17:08:25 +0530 [thread overview]
Message-ID: <20250131113830.925179-3-sourabhjain@linux.ibm.com> (raw)
In-Reply-To: <20250131113830.925179-1-sourabhjain@linux.ibm.com>
cmdline argument is not used in reserve_crashkernel_generic() so remove
it. Correspondingly, all the callers have been updated as well.
No functional change intended.
