bcachefs: Fix safe errors by default i.e. the start of automatic self healing: If errors=continue or fix_safe, we now automatically fix simple errors without user intervention. New error action option: fix_safe This replaces the existing errors=ro option, which gets a new slot, i.e. existing errors=ro users now get errors=fix_safe. This is currently only enabled for a limited set of errors - initially just disk accounting; errors we would never not want to fix, and we don't want to require user intervention (i.e. to make sure a bug report gets filed). Errors will still be counted in the superblock, so we (developers) will still know they've been occuring if a bug report gets filed (as bug reports typically include the errors superblock section). Eventually we'll be enabling this for a much wider set of errors, after we've done thorough error injection testing. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

This is currently only enabled for a limited set of errors - initially just disk accounting; errors we would never not want to fix, and we don't want to require user intervention (i.e. to make sure a bug report gets filed). Errors will still be counted in the superblock, so we (developers) will still know they've been occuring if a bug report gets filed (as bug reports typically include the errors superblock section). Eventually we'll be enabling this for a much wider set of errors, after we've done thorough error injection testing. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
