From 205f87f6b342444f722e4559d33318686f7df2ca Mon Sep 17 00:00:00 2001 From: Badari Pulavarty Date: Sun, 26 Mar 2006 01:38:00 -0800 Subject: [PATCH] change buffer_head.b_size to size_t Increase the size of the buffer_head b_size field (only) for 64 bit platforms. Update some old and moldy comments in and around the structure as well. The b_size increase allows us to perform larger mappings and allocations for large I/O requests from userspace, which tie in with other changes allowing the get_block_t() interface to map multiple blocks at once.
