From 1ce120dcefc056ce8af2486cebbb77a458aad4c3 Mon Sep 17 00:00:00 2001 From: Bernd Schubert Date: Thu, 23 Oct 2025 00:21:18 +0200 Subject: [PATCH] fuse: Always flush the page cache before FOPEN_DIRECT_IO write This was done as condition on direct_io_allow_mmap, but I believe this is not right, as a file might be open two times - once with write-back enabled another time with FOPEN_DIRECT_IO.
