There is no need to assign write permissions for this attribute. Here we can use read_attribute helper to define this attribute. ``` [Before] $ ll internal/gc_gens_pos -rw-r--r-- 1 root root 4096 Oct 28 15:27 internal/gc_gens_pos [After] $ ll internal/gc_gens_pos -r--r--r-- 1 root root 4096 Oct 28 17:27 internal/gc_gens_pos ``` Fixes: ac516d0e7db7 ("bcachefs: Add the status of bucket gen gc to sysfs") Signed-off-by: Hongbo Li Signed-off-by: Kent Overstreet --- diff --git a/fs/bcachefs/sysfs.c b/fs/bcachefs/sysfs.c index 4ab0ccba2ab5d..47ac8d5ab5626 100644 --- a/fs/bcachefs/sysfs.c +++ b/fs/bcachefs/sysfs.c @@ -146,7 +146,7 @@ write_attribute(trigger_journal_writes); write_attribute(trigger_btree_cache_shrink); write_attribute(trigger_btree_key_cache_shrink); write_attribute(trigger_freelist_wakeup); -rw_attribute(gc_gens_pos); +read_attribute(gc_gens_pos); read_attribute(uuid); read_attribute(minor);
