X-Git-Tag: v2.6.16-rc1~755 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=29ba17231222c42ca3df5424f43949e2a6fddec2;p=linux-2.6 [PATCH] ext3: use sbi instead of EXT3_SB() in resize code. There are places in the resize code in which EXT3_SB() macro is used after an statement like sbi = EXT3_SB(sb) is done. Inside the same function, both sbi and EXT3_SB() are used to reference the super block Altough it is not wrong, keeping it coherent increases legibility, IMHO.
