2005-01-20	[PATCH] fat: merge msdos_fs_{i,sb}.h into msdos_fs.h	Hirofumi Ogawa
	From Christoph Hellwig <hch@lst.de> We don't have the union in "struct inode" and "struct super_block", so we doesn't need xxx_fs_i.h and xxx_fs_sb.h anymore.

2004-10-19	[PATCH] FAT: rewrite the cache for file allocation table lookup	Hirofumi Ogawa
	This rewrites the cache stuff for file allocation table (FAT). This cache stocks the more pieces of FAT-chain by counting the number of contiguous data blocks. And if cache hit, since a block number can calculate without looking FAT-chain up, fat_get_block() become more fast. But if data blocks was fragmenting, unfortunately this cache is unuseful. read from block device [1st]# time dd if=/dev/hda6 of=/dev/null bs=1M count=2048 2147483648 bytes transferred in 229.524189 seconds (9356241 bytes/sec) real 3m49.557s, user 0m0.026s, sys 1m20.414s [2nd]# time dd if=/dev/hda6 of=/dev/null bs=1M count=2048 2147483648 bytes transferred in 229.539358 seconds (9355623 bytes/sec) real 3m49.647s, user 0m0.036s, sys 1m20.144s read from full contiguous file with this patch [1st]# time dd if=data of=/dev/null bs=1M count=2048 2147483648 bytes transferred in 337.959477 seconds (6354264 bytes/sec) real 5m37.970s, user 0m0.031s, sys 1m21.915s [2nd]# time dd if=data of=/dev/null bs=1M count=2048 2147483648 bytes transferred in 225.401699 seconds (9527362 bytes/sec) real 3m45.476s, user 0m0.027s, sys 1m19.286s read from full fragmented file with this patch [1st]# time dd if=data of=/dev/null bs=1M count=2048 2147483647 bytes transferred in 1146.529081 seconds (1873030 bytes/sec) real 19m6.538s, user 0m0.020s, sys 1m32.774s [2nd]# time dd if=data of=/dev/null bs=1M count=2048 2147483647 bytes transferred in 1045.084822 seconds (2054841 bytes/sec) real 17m25.152s, user 0m0.022s, sys 1m34.801s read from full contiguous file without this patch [1st]# time dd if=data of=/dev/null bs=1M count=2048 2147483648 bytes transferred in 348.144707 seconds (6168365 bytes/sec) real 5m48.169s, user 0m0.019s, sys 1m29.962s [2nd]# time dd if=data of=/dev/null bs=1M count=2048 2147483648 bytes transferred in 324.017361 seconds (6627681 bytes/sec) real 5m24.038s, user 0m0.023s, sys 1m20.602s read from full fragmented file without this patch [1st]# time dd if=data of=/dev/null bs=1M count=2048 2147483647 bytes transferred in 1156.845693 seconds (1856327 bytes/sec) real 19m16.855s, user 0m0.031s, sys 1m32.172s [2nd]# time dd if=data of=/dev/null bs=1M count=2048 2147483647 bytes transferred in 1066.518713 seconds (2013545 bytes/sec) real 17m46.526s, user 0m0.023s, sys 1m33.630s Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2003-12-29	[PATCH] FAT: Fix ->prev_free of fat (6/10)	Andrew Morton
	From: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> The -1 was documented as "there is no hint", so this patch uses -1 instead of 0 for FAT32 fsinfo.
2003-07-25	[PATCH] ->cluster_size cleanup (11/11)	Hirofumi Ogawa
	This renames ->cluster_size to ->sec_per_clus. Old ->cluster_size was "sectors per cluster". Adds a _real_ ->cluster_size.

2002-10-28	[PATCH] remove the fat_cvf stuff (2/3)	Hirofumi Ogawa
