The patch titled r/o bind mounts: elevate writer count for custom struct_file has been removed from the -mm tree. Its filename was r-o-bind-mounts-elevate-writer-count-for-custom-struct_file.patch This patch was dropped because an updated version will be merged ------------------------------------------------------ Subject: r/o bind mounts: elevate writer count for custom struct_file From: Dave Hansen <hansendc@xxxxxxxxxx> Some filesystems forego the use of normal vfs calls to create struct files. Make sure that these users elevate the mnt writer count. These probably don't have any real meaning because there is no real backing store for these mounts, but it is here for consistency.
