Only comments on the commit message. 1. Can you please put this and your 4/4 patch together. Since 4/4 comes is a result of this 3/4 patch, then they can be in one. 2. Please re-write the commit message to state what you did: Something like : "Remove the now unneeded check for ctl_table_size; it is safe to do so as it is now part of ctl_table_header. 3. Remember to mention the removal of the sentinel when you merge 3/4 and 4/4 > > Signed-off-by: Thomas Weißschuh <linux@weissschuh.net> > --- > fs/proc/proc_sysctl.c | 3 +-- > 1 file changed, 1 insertion(+), 2 deletions(-) > > diff --git a/fs/proc/proc_sysctl.c b/fs/proc/proc_sysctl.c > index fde7a2f773f0..4cdf98c6a9a4 100644 > --- a/fs/proc/proc_sysctl.c > +++ b/fs/proc/proc_sysctl.c > @@ -232,8 +232,7 @@ static int insert_header(struct ctl_dir *dir, struct ctl_table_header *header) > return -EROFS; > > /* Am I creating a permanently empty directory? */ > - if (header->ctl_table_size > 0 && > - sysctl_is_perm_empty_ctl_header(header)) { > + if (sysctl_is_perm_empty_ctl_header(header)) { > if (!RB_EMPTY_ROOT(&dir->root)) > return -EINVAL; > sysctl_set_perm_empty_ctl_header(dir_h); > > -- > 2.43.2 >

The type field is now part of the header so sysctl_is_perm_empty_ctl_header() can safely be executed even without any ctl_tables. Signed-off-by: Thomas Weißschuh <linux@weissschuh.net> --- fs/proc/proc_sysctl.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-)
