This fixes a device removal bug where the discard workers were still running while we're removing alloc info for that device. It's also a bit of hardening; we no longer allow writes to devices that are read-only. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

This fixes a device removal bug where the discard workers were still
running while we're removing alloc info for that device.

bcachefs: Add error code to defer option parsing 2024-07-14T23:00:12+00:00 Thomas Bertschinger tahbertschinger@gmail.com 2024-05-28T04:36:10+00:00 1c12d1caf8d627d8b791f4dc25af2522dac7cd10 This introduces a new error code, option_needs_open_fs, which is used to indicate that an attempt was made to parse a mount option prior to opening a filesystem, when that mount option requires an open filesystem in order to be validated. Returning this error results in bch2_parse_one_mount_opt() saving that option for later parsing, after the filesystem is opened.
