2023-10-23	bcachefs: Add safe versions of varint encode/decode	Kent Overstreet	1	-0/+3
	This adds safe versions of bch2_varint_(encode\|decode) that don't read or write past the end of the buffer, or varint being encoded. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23	bcachefs: New varints	Kent Overstreet	1	-0/+8
	Previous varint implementation used by the inode code was not nearly as fast as it could have been; partly because it was attempting to encode integers up to 96 bits (for timestamps) but this meant that encoding and decoding the length required a table lookup. Instead, we'll just encode timestamps greater than 64 bits as two separate varints; this will make decoding/encoding of inodes significantly faster overall.
