Re: [PATCH] ntfs: Drop cast

[Anton Altaparmakov]

Hi,

Thanks for your patch.  Your patch is obviously correct however I actually prefer to have the type casts in place because it clearly shows what the variable type being assigned to is so I find it makes the code more readable to cast void pointers to the target variable type so I don't have to go and look up the type higher up.  Having said that I don't feel that strongly about it so I have no real objection to the patch getting applied...

Best regards,

	Anton
