Subject: [PATCH v4 2/2] arm64/mm: Rename try_pgd_pgtable_alloc_init_mm
Date: Fri, 17 Oct 2025 10:44:37 +0530 [thread overview]
Message-ID: <20251017051437.2836080-3-linu.cherian@arm.com> (raw)
In-Reply-To: <20251017051437.2836080-1-linu.cherian@arm.com>
With BUG_ON in pgd_pgtable_alloc_init_mm moved up to higher layer,
gfp flags is the only difference between try_pgd_pgtable_alloc_init_mm
and pgd_pgtable_alloc_init_mm. Hence rename the "try" version
to pgd_pgtable_alloc_init_mm_gfp.
