2024-05-08bcachefs: ob_dev()Kent Overstreet1-0/+7
Wrapper around bch2_dev_have_ref() for open_buckets; we do guarantee that the device an open_bucket points to exists. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-05-08bcachefs: bch2_dev_iterate()Kent Overstreet1-0/+8
New helper for getting refs to devices as we iterate. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-05-08bcachefs: bch2_check_alloc_key() -> bch2_dev_tryget_noerror()Kent Overstreet1-0/+25
More elimination of bch2_dev_bkey_exists() usage. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-05-08bcachefs: bch2_dev_tryget()Kent Overstreet1-0/+20
Most uses of bch2_dev_bkey_exists() are going away, where we assume that because a key references a device the device most exist - instead, we'll be explicitly checking if the device exists and getting a reference to it. This adds the new helpers. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2024-05-08bcachefs: New helpers for device refcountsKent Overstreet1-4/+18
This will be used in the next patch for adding some new debug mode asserts. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-05-08bcachefs: member helper cleanupsKent Overstreet1-10/+22
Some renaming for better consistency bch2_member_exists -> bch2_member_alive bch2_dev_exists -> bch2_member_exists bch2_dev_exsits2 -> bch2_dev_exists bch_dev_locked -> bch2_dev_locked bch_dev_bkey_exists -> bch2_dev_bkey_exists new helper - bch2_dev_safe Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-05-08bcachefs: bucket_valid()Kent Overstreet1-0/+2
cut out a branch from doing it the obvious way Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-05-06bcachefs: Fix lifetime issue in device iterator helpersKent Overstreet1-2/+2
bch2_get_next_dev() and bch2_get_next_online_dev() iterate over devices, dropping and taking refs as they go; we can't access the previous device (for ca->dev_idx) after we've dropped our ref to it, unless we take rcu_read_lock() first. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-04-17bcachefs: Fix bch2_dev_btree_bitmap_marked_sectors() shiftKent Overstreet1-3/+3
Fixes: 27c15ed297cb bcachefs: bch_member.btree_allocated_bitmap Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-04-14bcachefs: bch_member.btree_allocated_bitmapKent Overstreet1-0/+21
This adds a small (64 bit) per-device bitmap that tracks ranges that have btree nodes, for accelerating btree node scan if it is ever needed. - New helpers, bch2_dev_btree_bitmap_marked() and bch2_dev_bitmap_mark(), for checking and updating the bitmap - Interior btree update path updates the bitmaps when required - The check_allocations pass has a new fsck_err check, btree_bitmap_not_marked - New on disk format version, mi_btree_mitmap, which indicates the new bitmap is present - Upgrade table lists the required recovery pass and expected fsck error - Btree node scan uses the bitmap to skip ranges if we're on the new version Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-11-01bcachefs: bch_sb_field_errorsKent Overstreet1-1/+1
Add a new superblock section to keep counts of errors seen since filesystem creation: we'll be addingcounters for every distinct fsck error. The new superblock section has entries of the for [ id, count, time_of_last_error ]; this is intended to let us see what errors are occuring - and getting fixed - via show-super output. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-11-01bcachefs: Add IO error counts to bch_memberKent Overstreet1-1/+41
We now track IO errors per device since filesystem creation. IO error counts can be viewed in sysfs, or with the 'bcachefs show-super' command. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Rename bch_sb_field_members -> bch_sb_field_members_v1Hunter Shaffer1-2/+1

2023-10-22bcachefs: New superblock section members_v2Hunter Shaffer1-0/+5
members_v2 has dynamically resizable entries so that we can extend bch_member. The members can no longer be accessed with simple array indexing Instead members_v2_get is used to find a member's exact location within the array and returns a copy of that member. Alternatively member_v2_get_mut retrieves a mutable point to a member. Signed-off-by: Hunter Shaffer <huntershaffer182456@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Add new helper to retrieve bch_member from sbHunter Shaffer1-0/+2
Prep work for introducing bch_sb_field_members_v2 - introduce new helpers that will check for members_v2 if it exists, otherwise using v1 Signed-off-by: Hunter Shaffer <huntershaffer182456@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: sb-members.cKent Overstreet1-0/+176
Split out a new file for bch_sb_field_members - we'll likely want to move more code here in the future. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
