padata_alloc | padata_alloc - allocate and initialize a padata instance and specify* cpumasks for serial and parallel workers |
z3fold_create_pool | z3fold_create_pool() - create a new z3fold pool*@name: pool name*@gfp: gfp flags when allocating the z3fold pool structure*@ops: user-defined operations for the z3fold pool* Return: pointer to the new z3fold pool or NULL if the metadata allocation* failed. |
z3fold_destroy_pool | z3fold_destroy_pool() - destroys an existing z3fold pool*@pool: the z3fold pool to be destroyed* The pool should be emptied before this function is called. |
sb_init_dio_done_wq | Create workqueue for deferred direct IO completions. We allocate the* workqueue when it's first needed. This avoids creating workqueue for* filesystems that don't need it and also allows us to create the workqueue |
fscrypt_init | scrypt_init() - Set up for fs encryption. |
fsverity_exit_workqueue | |
bioset_exit | set_exit - exit a bioset initialized with bioset_init()* May be called on a zeroed but uninitialized bioset (i.e. allocated with* kzalloc()). |
generic_shutdown_super | generic_shutdown_super - common helper for ->kill_sb()*@sb: superblock to kill* generic_shutdown_super() does all fs-independent work on superblock* shutdown |
