Subject: revert mkfs change; might run out of inodes, but large number of inodes
X-Git-Tag: v3.1.5~72
X-Git-Url: http://zhaoyanbai.com/repos/?a=commitdiff_plain;h=699e4345eac9954b8e540c15f6a60067b55b44b7;p=minix.git

revert mkfs change; might run out of inodes, but large number of inodes
makes mkfs not want to mkfs large filesystems.

find optimal formula (e.g. dynamic capping of no. of inodes) later.
