From 263cf578049708a115b3ca58e46b7e5d20763866 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Thu, 30 May 2024 21:20:53 +0100 Subject: [PATCH] befs: Convert befs_symlink_read_folio() to use folio_end_read() This is slightly more efficient than separate calls to folio_mark_uptodate() and folio_unlock(), and it's easier to read. Get rid of the call to folio_set_error() as nobody will check this flag.
