Subject: Re: [RFC][PATCH v3 16/22] mm, m32r: add gfp flags variant of pmd and pte allocations
Date: Fri, 18 Mar 2011 20:04:52 +0000 [thread overview]
Message-ID: <20110318200452.GQ4746@prasad-kvm> (raw)
In-Reply-To: <20110318200401.GP4746@prasad-kvm>
- Added function __pmd_alloc_one which is same as pmd_alloc_one, but accepts
an extra argument for gfp_t flag.
- Added function __pte_alloc_one_kernel to allocated zeroed page using
allocation flag passed as an argument.
- Changed pte_alloc_one_kernel to call __pte_alloc_one_kernel using
GFP_KERNEL allocation flag.
- Helps in fixing the Bug 30702
