2023-10-22bcachefs: BTREE_ITER_SLOTS isn't a type of btree iterKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Trivial cleanupKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Convert a BUG_ON() to a warningKent Overstreet
We shouldn't ever be writing past i_size - but, apparently there's still a bug to track down. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Handle bio_iov_iter_get_pages() returning unaligned bioKent Overstreet
If the user buffer isn't aligned to the filesystem block size, on a large enough IO - where it won't fit into a single bio - bio_iov_iter_get_pages() won't necessarily return a bio with the proper alignment. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Add support for FALLOC_FL_INSERT_RANGEKent Overstreet
Somewhat tricky and ugly, because iterating over extents backwards is a pain. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Don't write past eofKent Overstreet
When converting from PAGE_SIZE to block_size, the .mkwrite path was missed Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Improved bch2_fcollapse()Kent Overstreet
Move extents instead of copying them - this way, we can iterate over only live extents, not the entire keyspace. Also, this means we can mostly skip running triggers. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Inline some fast pathsKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Check alignment in write pathKent Overstreet
Also - fix alignment in bch2_set_page_dirty() Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: ReflinkKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Refactor bch2_extent_trim_atomic() for reflinkKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Mark space as unallocated on write failureKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Truncate/fpunch now works on block boundaries, not pageKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Count reserved extents as holesKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Handle partial pages in seek data/holeKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Change buffered write path to write to partial pagesKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Change __bch2_writepage() to not write to holesKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Fix bch2_seek_data()Kent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Refactor various code to not be extent specificKent Overstreet
With reflink, various code now has to handle both KEY_TYPE_extent or KEY_TYPE_reflink_v - so, convert it to be generic across all keys with pointers. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Dont't call bch2_trans_begin_updates() in bch2_extent_update()Kent Overstreet
Prep work for reflink - for reflink, we're going to be using bch2_extent_update() with other updates in the same transaction. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Add offset_into_extent param to bch2_read_extent()Kent Overstreet
With reflink, we'll no longer be able to calculate the offset of the data we want into the extent we're reading from from the extent pos and the iter pos - we'll have to pass it in separately. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Track dirtyness at sector level, not pageKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Kill page_state_cmpxchgKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Always touch page state with page lockedKent Overstreet
This will mean we don't have to use cmpxchg for modifying page state, which will simplify a fair amount of code Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Kill direct access to bi_io_vecKent Overstreet
Switch to always using bio_add_page(), which merges contiguous pages now that we have multipage bvecs. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Make bkey types globally uniqueKent Overstreet
this lets us get rid of a lot of extra switch statements - in a lot of places we dispatch on the btree node type, and then the key type, so this is a nice cleanup across a lot of code. Also improve the on disk format versioning stuff. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Fix a btree iter usage errorKent Overstreet
previously, if the code traversed to the next btree node, that could return an error (due to lock restarts) - which was not being checked for. fix is to rework it so it never iterates past the current leaf node, and pops an assertion if it ever sees an error.
