Now that all filesystems have been converted over to stop using the
kthread freezer APIs we can remove FS_AUTOFREEZE and its check.
The following Coccinelle rule was used as to remove the flag:
spatch --sp-file remove-fs-autofreezeflag.cocci --in-place --timeout 120 --dir fs/ --jobs 12 --use-gitgrep
@ rm_auto_flag @
expression E1;
identifier fs_type;
@@
struct file_system_type fs_type = {
.fs_flags = E1
- | FS_AUTOFREEZE
,
};
