9p/fs: Different branch return the same value

[PATCH] 9p/fs: Different branch return the same value

Posted by Rex Nie 1 week, 1 day ago

The same code is executed when the condition ret < 0 is true or false.
Remove the if branch and just return v9fs_init_inode_cache(). This
does not change the semantics of the original code.

Hi,

a similar patch has already been sent.

See [1], which is the v2 of the patch and goes one step further.
