From 2d288745ebc202d7ac4905cba4a540549dc8044e Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Tue, 23 Apr 2024 11:58:09 -0700 Subject: bcachefs: Fix type of flags parameter for some ->trigger() implementations When building with clang's -Wincompatible-function-pointer-types-strict (a warning designed to catch potential kCFI failures at build time), there are several warnings along the lines of: fs/bcachefs/bkey_methods.c:118:2: error: incompatible function pointer types initializing 'int (*)(struct btree_trans *, enum btree_id, unsigned int, struct bkey_s_c, struct bkey_s, enum btree_iter_update_trigger_flags)' with an expression of type 'int (struct btree_trans *, enum btree_id, unsigned int, struct bkey_s_c, struct bkey_s, unsigned int)' [-Werror,-Wincompatible-function-pointer-types-strict] 118 | BCH_BKEY_TYPES() | ^~~~~~~~~~~~~~~~ fs/bcachefs/bcachefs_format.h:394:2: note: expanded from macro 'BCH_BKEY_TYPES' 394 | x(inode, 8) \ | ^~~~~~~~~~~~~~~~~~~~~~~~~~ fs/bcachefs/bkey_methods.c:117:41: note: expanded from macro 'x' 117 | #define x(name, nr) [KEY_TYPE_##name] = bch2_bkey_ops_##name, | ^~~~~~~~~~~~~~~~~~~~ :277:1: note: expanded from here 277 | bch2_bkey_ops_inode | ^~~~~~~~~~~~~~~~~~~ fs/bcachefs/inode.h:26:13: note: expanded from macro 'bch2_bkey_ops_inode' 26 | .trigger = bch2_trigger_inode, \ | ^~~~~~~~~~~~~~~~~~ There are several functions that did not have their flags parameter converted to 'enum btree_iter_update_trigger_flags' in the recent unification, which will cause kCFI failures at runtime because the types, while ABI compatible (hence no warning from the non-strict version of this warning), do not match exactly. Fix up these functions (as well as a few other obvious functions that should have it, even if there are no warnings currently) to resolve the warnings and potential kCFI runtime failures.
