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

From: Wang Shilong <[email protected]>

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

Ideally, use RESEND if you haven't changed the patch series since the last time you've sent it. If you have changed it, please use [PATCH v2], [PATCH v3], etc.

Thanks,

I get it..
Thanks, thanks every one for teaching me so much...

Now i am trying to do something for ext4 development in my leisure time.. Since i don't know anything about filesystem before.. i have to study about it from minix to ext2..ext3..ext4..btrfs..

However, it still seems a little hard for me to figure everything out just by reading code... So i wonder where i can get
some papers or articles about the new concept of filesystems.. for example extent management or something else for ext4..etc Maybe it helps a lot for me...
