macros in inode_set_cached_link() - Use debug-only asserts around fd allocation and install - Place f_ref to 3rd cache line in struct file to resolve false sharing Cleanups: - Start using anon_inode_getfile_fmode() helper in various places - Don't take f_lock during SEEK_CUR if exclusion is guaranteed by f_pos_lock - Add unlikely() to kcmp() - Remove legacy ->remount_fs method from ecryptfs after port to the new mount api - Remove invalidate_inodes() in favour of evict_inodes() - Simplify ep_busy_loopER by removing unused argument - Avoid mmap sem relocks when coredumping with many missing pages - Inline getname() - Inline new_inode_pseudo() and de-staticize alloc_inode() - Dodge an atomic in putname if ref == 1 - Consistently deref the files table with rcu_dereference_raw() - Dedup handling of struct filename init and refcounts bumps - Use wq_has_sleeper() in end_dir_add() - Drop the lock trip around I_NEW wake up in evict() - Load the ->i_sb pointer once in inode_sb_list_{add,del} - Predict not reaching the limit in alloc_empty_file() - Tidy up do_sys_openat2() with likely/unlikely - Call inode_sb_list_add() outside of inode hash lock - Sort out fd allocation vs dup2 race commentary - Turn page_offset() into a wrapper around folio_pos() - Remove locking in exportfs around ->get_parent() call - try_lookup_one_len() does not need any locks in autofs - Fix return type of several functions from long to int in open - Fix return type of several functions from long to int in ioctls Fixes: - Fix watch queue accounting mismatch" * tag
