From 37d369fa97cc0774ea4eab726d16bcb5fbe3a104 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Sun, 23 Nov 2025 22:05:15 +0000 Subject: fs: Add uoff_t In a recent commit, I inadvertently changed a comparison from being an unsigned comparison (on 64-bit systems) to being a signed comparison (which it had always been on 32-bit systems). This led to a sporadic fstests failure. To make sure this comparison is always unsigned, introduce a new type, uoff_t which is the unsigned version of loff_t. Generally file sizes are restricted to being a signed integer, but in these two places it is convenient to pass -1 to indicate "up to the end of the file".
