Subject: [RFC][PATCH v2 00/23] (alpha) __vmalloc: add gfp flags variant of pte and pmd allocation
Date: Mon, 14 Mar 2011 17:27:10 +0000 [thread overview]
Message-ID: <AANLkTik3qn-RVUTZp5+gTk+wB9SO_MsxySHEwE8Yzi-e@mail.gmail.com> (raw)
__vmalloc: propagating GFP allocation flag.
- adds functions to allow caller to pass the GFP flag for memory allocation
- helps in fixing the Bug 30702 (__vmalloc(GFP_NOFS) can callback
file system evict_inode).
