Subject: [PATCH v7 04/11] hugetlb: Introduce generic version of huge_ptep_get_and_clear
Date: Thu, 20 Sep 2018 06:03:51 +0000 [thread overview]
Message-ID: <20180920060358.16606-5-alex@ghiti.fr> (raw)
In-Reply-To: <20180920060358.16606-1-alex@ghiti.fr>
arm, ia64, sh, x86 architectures use the
same version of huge_ptep_get_and_clear, so move this generic
implementation into asm-generic/hugetlb.h.

Subject: [PATCH v7 04/11] hugetlb: Introduce generic version of huge_ptep_get_and_clear
Date: Thu, 20 Sep 2018 06:03:51 +0000 [thread overview]
Message-ID: <20180920060358.16606-5-alex@ghiti.fr> (raw)
In-Reply-To: <20180920060358.16606-1-alex@ghiti.fr>
arm, ia64, sh, x86 architectures use the
same version of huge_ptep_get_and_clear, so move this generic
implementation into asm-generic/hugetlb.h.
