Subject: [PATCH] minix v3: fix superblock definition
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f4fa27c16ba9b6910c5b815e5c13a7e8249277f0;p=linux-beck.git

[PATCH] minix v3: fix superblock definition

Somehow we got the layout of the v3 superblock wrong, which causes crashes due
to overindexing of the buffer_head array in statfs on large fielsystems.
