Subject: Ext2: remove the overhead check about sb in the function ext2_new_blocks
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=98783e453c1084527388ec1a7f6367cd6aabbe63;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

Ext2: remove the overhead check about sb in the function ext2_new_blocks

It can be guranteed that inode->i_sb should not be null in vfs.
So here the check about it is overhead.
