bcachefs was marked 'externally maintained' in 6.17 but the code
remained to make the transition smoother.
It's now a DKMS module, making the in-kernel code stale, so remove
it to avoid any version confusion.

Add a tracepoint for any time we return an error and unwind.

Currently, device removal has to scan all metadata for pointers to the
device being removed.
Add a new method, with the same interface as bch2_dev_data_drop(), that
scans by backpointers instead - this will drastically speed up device
removal.

bcachefs: Kill btree_iter.trans2025-04-02T14:24:34+00:00Kent Overstreetkent.overstreet@linux.dev2025-03-21T19:18:51+00:00urn:sha1:9180ad2e161b7030e0af78fd2266cbcefe81e652
This was planned to be done ages ago, now finally completed; there are
places where we have quite a few btree_trans objects on the stack, so
this reduces stack usage somewhat.

bcachefs: Add a progress indicator to bch2_dev_data_drop()2025-03-15T01:02:12+00:00Kent Overstreetkent.overstreet@linux.dev2025-02-06T21:25:29+00:00urn:sha1:491eda63947335e4f779443b524ae6086b0de052
This code needs quite a bit of work: we don't want to be walking all
metadata in the filesystem, we should just be walking backpointers, and
it should be switched to a data ioctl that can report progress via a
file descriptor, not the system console.
But that'll take more work - before we can safely walk only backpointers
we need to change device add to not reuse device indexes, since with
that change accounting being wrong introduces the possibility of
removing a device that still has pointers.

bcachefs: iter/update/trigger/str_hash flag cleanup2024-05-08T21:29:18+00:00Kent Overstreetkent.overstreet@linux.dev2024-04-07T22:05:34+00:00urn:sha1:5dd8c60e1e044816d789098ce2454a130e06b03d
Combine iter/update/trigger/str_hash flags into a single enum, and
x-macroize them for a to_text() function later.
These flags are all for a specific iter/key/update context, so it makes
sense to group them together - iter/update/trigger flags were already
given distinct bits, this cleans up and unifies that handling.

Repurposing standard error codes in bcachefs code is banned in new code,
and we need to get rid of the remaining ones - private error codes give
us much better error messages.

BTREE_INSERT flags are actually transaction commit flags - rename them
for clarity.
