bch2_accounting_mem_insert() drops and retakes mark_lock; thus, we need to check if the entry in question has already been inserted. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

The commit 65bd4423 ("bcachefs: bch2_btree_insert_trans() no longer specifies BTREE_ITER_cached") removes BTREE_ITER_cached from bch2_btree_insert_trans, which causes the update_inode function from bcachefs-tools to take a long time (~20s). Add an iter_flags parameter to bch2_btree_insert, so the users can specify iter update trigger flags, such as BTREE_ITER_cached.

Add a new ioctl that can return the new accounting counter types; it takes as input a bitmask of accounting types to return. This will be used for returning e.g. compression accounting and rebalance_work accounting. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

By removing the early-exit when REMAP_FILE_DEDUP is set, we should be able to support the fideduperange ioctl, albeit less efficiently than if we handled some of the extent locking and comparison logic inside bcachefs. Extent comparison logic already exists inside of `__generic_remap_file_range_prep`. Signed-off-by: Reed Riley <reed@riley.engineer> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

In this patch we add the FS_IOC_GETVERSION ioctl for getting i_generation from inode, after that, users can list file's generation number by using "lsattr". Signed-off-by: Hongbo Li <lihongbo22@huawei.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Add trace_bch2_sync_fs() and trace_bch2_fsync() implementations.

We already using mapping_set_error() in bch2_writepage_io_done(), so all we need to do is to use file_check_and_advance_wb_err() when handling fsync() requests in bch2_fsync(). Signed-off-by: Youling Tang <tangyouling@kylinos.cn> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Commit 0c0cbfdb dropped the ctx->pos update before the call to dir_emit. This breaks the userspace implementation, causing the directory reads to be stuck in an infinite loop. This doesn't happen in the kernel because the vfs handles the updates to ctx->pos, but in the fuse implementation nobody updates it.

We now read the line from the buffer atomically, which means we have to allow the buffer to grow past STDIO_REDIRECT_BUFSIZE if we're waiting for a full line - this behaviour is necessary for stdio_redirect_readline_timeout() in the next patch.

fsck_err() now optionally takes a btree_trans; if the current thread has one, it is required that it be passed. The next patch will use this to unlock when waiting for user input. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Blocking the journal was needed to finish checking old style accounting, but that code is gone and it's not needed in the alloc rewrite, mark_lock is sufficient for synchronization. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

The btree write buffer takes as input keys from the journal, sorts them, deduplicates them, and flushes them back to the btree in sorted order. The disk space accounting rewrite is moving accounting to normal btree keys, with update (in this case deltas) accumulated in the write buffer and then flushed to the btree; but this is going to increase the number of keys handled by the write buffer by perhaps as much as a factor of 3x-5x. The overhead from copying around and sorting this many keys would cause a significant performance regression, but: there is huge locality in updates to accounting keys that we can take advantage of. Instead of appending accounting keys to the list of keys to be sorted, this patch adds an eytzinger search tree of recently seen accounting keys. We look up the accounting key in the eytzinger search tree and apply the delta directly, adding it if it doesn't exist, and periodically prune the eytzinger tree of unused entries.

This adds per-compression-type accounting of compressed and uncompressed size as well as number of extents - meaning we can now see compression ratio (without walking the whole filesystem). Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Rewrite fsck/gc for the new accounting scheme. This adds a second set of in-memory accounting counters for gc to use; like with other parts of gc we run all trigger in TRIGGER_GC mode, then compare what we calculated to existing in-memory accounting at the end.

More ripping out of the old disk space accounting. Note that the new disk space accounting is incompatible with the old, and writing out old style disk space accounting with the new code is infeasible. This means upgrading and downgrading past this version requires regenerating accounting. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
