Miklos, The first solution that we discussed for removing FMODE_NONOTIFY from overlayfs real files using file_fake container got complicated. This alternative solution is less intrusive to vfs and all the vfs code should remian unaffected expect for the special fsnotify case that we want to fix. Thanks, Amir. Changes since v1: - Drop the file_fake container - Leave f_path fake and special case only fsnotify [1] https://github.com/amir73il/linux/commits/ovl_real_path Amir Goldstein (3): fs: rename FMODE_NOACCOUNT to FMODE_INTERNAL fs: introduce f_real_path() helper ovl: enable fsnotify events on underlying real files Documentation/filesystems/locking.rst | 3 ++- Documentation/filesystems/vfs.rst | 3 ++- fs/file_table.c | 29 ++++++++++++++++++++++++--- fs/internal.h | 5 +++-- fs/namei.c | 2 +- fs/open.c | 2 +- fs/overlayfs/file.c | 4 ++-- fs/overlayfs/super.c | 27 ++++++++++++++++--------- include/linux/dcache.h | 11 ++++++---- include/linux/fs.h | 8 +++++--- include/linux/fsnotify.h | 6 ++++-- 11 files changed, 71 insertions(+), 29 deletions(-) -- 2.34.1
