https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D238700 --- Comment #3 from Alan <alan.murtagh@vorteil.io> --- (In reply to Conrad Meyer from comment #1) The entirety of the code I posted is new.=20 Sorry, I was unclear. The "before" and "after" sections in my code snippet = do not refer to "before my change" and "after my change". Rather, the before section is for loading in blocks before the read region and the after secti= on is for loading in blocks afterwards. The purpose of these sections is to en= sure that when loading a block that would be partway through a page, extra blocks are loaded into the cache before and after as necessary. (In reply to Konstantin Belousov from comment #2) I cannot reproduce the issue in UFS. I can't reproduce it in ext2 with 4KiB blocks either, so I think you're right about why. --=20 You are receiving this mail because: You are the assignee for the bug.=
