From 582a3bf999df662c0e0fa4717ce7559f16d7b93b Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 12 Feb 2024 07:24:05 -0500 Subject: [PATCH] filelock: always define for_each_file_lock() ...and eliminate the stub version when CONFIG_FILE_LOCKING is disabled. This silences the following warning that crept in recently: fs/ceph/locks.c: In function 'ceph_count_locks': fs/ceph/locks.c:380:27: error: unused variable 'lock' [-Werror=unused-variable] 380 | struct file_lock *lock; Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202402062210.3YyBVGF1-lkp@intel.com/ Fixes: 75cabec0111b ("filelock: add some new helper functions") Signed-off-by: Jeff Layton Link: https://lore.kernel.org/r/20240212-flsplit3-v1-1-019f0ad6bf69@kernel.org Signed-off-by: Christian Brauner --- include/linux/filelock.h | 8 +++----- 1 file changed, 3 insertions(+), 5 deletions(-) diff --git a/include/linux/filelock.h b/include/linux/filelock.h index aabd4bdf7eba..daee999d05f3 100644 --- a/include/linux/filelock.h +++ b/include/linux/filelock.h @@ -180,9 +180,6 @@ static inline void locks_wake_up(struct file_lock *fl) wake_up(&fl->c.flc_wait); } -/* for walking lists of file_locks linked by fl_list */ -#define for_each_file_lock(_fl, _head) list_for_each_entry(_fl, _head, c.flc_list) - /* fs/locks.c */ void locks_free_lock_context(struct inode *inode); void locks_free_lock(struct file_lock *fl); @@ -283,8 +280,6 @@ static inline void locks_wake_up(struct file_lock *fl) { } -#define for_each_file_lock(_fl, _head) while(false) - static inline void locks_free_lock_context(struct inode *inode) { @@ -414,6 +409,9 @@ locks_inode_context(const struct inode *inode) #endif /* !CONFIG_FILE_LOCKING */ +/* for walking lists of file_locks linked by fl_list */ +#define for_each_file_lock(_fl, _head) list_for_each_entry(_fl, _head, c.flc_list) + static inline int locks_lock_file_wait(struct file *filp, struct file_lock *fl) { return locks_lock_inode_wait(file_inode(filp), fl);
