now that type signatures are unified, redundant Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
-
Kent Overstreet authored
New flag so that triggers can distinguish whether we're running transactional or atomic triggers (or gc) - unifying the callbacks. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Prep work for disk space accounting rewrite: we're going to want to use a single callback for both of our current triggers, so we need to change them to have the same type signature first. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

BCH_MEMBER_DURABILITY() was not present initially; a value of 0 means use the default, nonzero means use v - 1. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Use the new bch_member->seq, sb->write_time fields to detect split brain and kick out devices when necessary. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
-
Kent Overstreet authored
Add new fields for split brain detection: - bch_member->seq, which tracks the sequence number of the last superblock write that happened to each member device - bch_sb->write_time, which tracks the time of the last superblock write, to allow detection of when two members have diverged but had the same number of superblock writes.

nochanges means "we cannot issue writes at all"; it's possible to go into a pseudo read-write mode where we pin dirty metadata in memory, which is used for fsck in dry run mode and doing journal replay on a read only mount, but we do not want to allow an actual read-write mount in nochanges mode. But we do always want to allow early read-write, during recovery - this patch clarifies that. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Now that we have dynamically resizable btree paths, check_directory_structure() can check one path - inode up to the root - in a single transaction. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
-
Kent Overstreet authored
reattach_inode() was broken w.r.t. snapshots - we'd lookup the subvolume to look up lost+found, but if we're in an interior node snapshot that didn't make any sense. Instead, this adds a dirent path for creating in a specific snapshot, skipping the subvolume; and we also make sure to create lost+found in the root snapshot, to avoid conflicts with lost+found being created in overlapping snapshots.

XXX: we're allocating memory with btree locks held - bad We need to plumb through an error path so we can do allocate_dropping_locks() - but we're merging this now because it fixes a transaction path overflow caused by indirect extent fragmentation, and the resize path is rare. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Since the btree_paths array is now about to become growable, we have to be careful not to refer to paths by pointer across contexts where they may be reallocated. This fixes the remaining btree_interior_update() paths - split and merge. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Start to plumb through dynamically growable btree_paths; this patch replaces most BTREE_ITER_MAX references with trans->nr_paths. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

the reflink triggers are also bumping up against the maximum number of paths in a transaction - and generating proportional numbers of updates. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

- Some tweaks to greatly reduce locking overhead for the list of btree transactions, so that it can always be enabled: leave btree_trans objects on the list when they're on the percpu single item freelist, and only check for duplicates in the same process when CONFIG_BCACHEFS_DEBUG is enabled - don't zero out the full btree_trans() unless we allocated it from the mempool Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Upcoming patches are going to be changing trans->paths to a reallocatable buffer. We need to guard against use after free when it's used by other threads; this introduces RCU protection to those paths and changes them to check for trans->paths == NULL Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
