This is necessary for erasure coded pointers to devices that have been removed. Signed-off-by: Kent Overstreet

bcachefs: Make bkey_fsck_err() a wrapper around fsck_err()

2024-08-14T03:00:50+00:00

bkey_fsck_err() was added as an interface that looks like fsck_err(), but previously all it did was ensure that the appropriate error counter was incremented in the superblock. This is a cleanup and bugfix patch that converts it to a wrapper around fsck_err(). This is needed to fix an issue with the upgrade path to disk_accounting_v3, where the "silent fix" error list now includes bkey_fsck errors; fsck_err() handles this in a unified way, and since we need to change printing of bkey fsck errors from the caller to the inner bkey_fsck_err() calls, this ends up being a pretty big change. Als,, rename .invalid() methods to .validate(), for clarity, while we're changing the function signature anyways (to drop the printbuf argument). Signed-off-by: Kent Overstreet

bcachefs: s/bkey_invalid_flags/bch_validate_flags

We're about to start using bch_validate_flags for superblock section validation - it's no longer bkey specific. Signed-off-by: Kent Overstreet

bcachefs: Prep work for variable size btree node buffers

2024-01-21T18:27:10+00:00

bcachefs btree nodes are big - typically 256k - and btree roots are pinned in memory. As we're now up to 18 btrees, we now have significant memory overhead in mostly empty btree roots. And in the future we're going to start enforcing that certain btree node boundaries exist, to solve lock contention issues - analagous to XFS's AGIs. Thus, we need to start allocating smaller btree node buffers when we can. This patch changes code that refers to the filesystem constant c->opts.btree_node_size to refer to the btree node buffer size - btree_buf_bytes() - where appropriate. Signed-off-by: Kent Overstreet
