From e9cd1d9a34131fb56bef469d4e1cd31bd1b515e2 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 1 Mar 2023 12:02:08 +0100 Subject: ext2: Correct maximum ext2 filesystem block size Ext2 has traditionally supported filesystem block sizes upto page size or upto 65536. Macro EXT2_MAX_BLOCK_SIZE is set to 4096, however that is never used in ext2 so practically we always allowed whatever sb_set_blocksize() accepted. Fix value of EXT2_MAX_BLOCK_SIZE because it will be used in the next patch.
