From 383aa543c2f46f245d652c0e5c77390f07ece657 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Thu, 6 Jul 2017 07:02:29 -0400 Subject: [PATCH] fs: convert __generic_file_fsync to use errseq_t based reporting Many simple, block-based filesystems use generic_file_fsync as their fsync operation. Some others (ext* and fat) also call this function to handle syncing out data. Switch this code over to use errseq_t based error reporting so that all of these filesystems get reliable error reporting via fsync, fdatasync and msync.
