From a0f62ac6362c168754cccb36f196b3dfbddc3bc3 Mon Sep 17 00:00:00 2001 From: Takashi Sato Date: Sun, 26 Mar 2006 01:37:52 -0800 Subject: [PATCH] 2TB files: add blkcnt_t Add blkcnt_t as the type of inode.i_blocks. This enables you to make the size of blkcnt_t either 4 bytes or 8 bytes on 32 bits architecture with CONFIG_LSF. - CONFIG_LSF Add new configuration parameter. - blkcnt_t On h8300, i386, mips, powerpc, s390 and sh that define sector_t, blkcnt_t is defined as u64 if CONFIG_LSF is enabled; otherwise it is defined as unsigned long. On other architectures, it is defined as unsigned long. - inode.i_blocks Change the type from sector_t to blkcnt_t.
