Subject: block: Remove check of PageError
X-Git-Tag: block-6.0-2022-08-12~45^2~57
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=0e00fa5f83606064f3b7bb11d9608d216ac6b45a;p=linux-2.6-block.git

block: Remove check of PageError

If read_mapping_page() sees a page with PageError set, it returns a
PTR_ERR().  Checking PageError again is simply dead code.
