2023-10-23bcachefs: Heap allocate btree_transKent Overstreet1-2/+2
We're using more stack than we'd like in a number of functions, and btree_trans is the biggest object that we stack allocate. But we have to do a heap allocatation to initialize it anyways, so there's no real downside to heap allocating the entire thing. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Log truncate operationsKent Overstreet1-0/+1
Previously, we guaranteed atomicity of truncate after unclean shutdown with the BCH_INODE_I_SIZE_DIRTY flag - which required a full scan of the inodes btree. Recently the deleted inodes btree was added so that we no longer have to scan for deleted inodes, but truncate was unfinished and that change left it broken. This patch uses the new logged operations btree to fix truncate atomicity; we now log an operation that can be replayed at the start of a truncate.

2023-10-23bcachefs: BTREE_ID_logged_opsKent Overstreet1-0/+111
Add a new btree for long running logged operations - i.e. for logging operations that we can't do within a single btree transaction, so that they can be resumed if we crash. Keys in the logged operations btree will represent operations in progress, with the state of the operation stored in the value. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
