Christoph Hellwig 6ab455eeaf [XFS] Fix memory corruption with small buffer reads ... When we have multiple buffers in a single page for a blocksize == pagesize filesystem we might overwrite the page contents if two callers hit it shortly after each other. To prevent that we need to keep the page locked until I/O is completed and the page marked uptodate. Thanks to Eric Sandeen for triaging this bug and finding a reproducible testcase and Dave Chinner for additional advice. This should fix kernel.org bz #10421.
