bcache: Fix a journal replay bug

2014-08-04T22:23:02Z

journal replay wansn't validating pointers with bch_extent_invalid() before derefing, fixed Signed-off-by: Kent Overstreet

bcache: remove nested function usage

2014-03-18T19:39:28Z

Uninlined nested functions can cause crashes when using ftrace, as they don't follow the normal calling convention and confuse the ftrace function graph tracer as it examines the stack. Also, nested functions are supported as a gcc extension, but may fail on other compilers (e.g. llvm). Signed-off-by: John Sheu

bcache: Kill bucket->gc_gen

2014-03-18T19:24:54Z

gc_gen was a temporary used to recalculate last_gc, but since we only need bucket->last_gc when gc isn't running (gc_mark_valid = 1), we can just update last_gc directly. Signed-off-by: Kent Overstreet

bcache: Add a real GC_MARK_RECLAIMABLE

2014-03-18T19:22:36Z

This means the garbage collection code can better check for data and metadata pointers to the same buckets. Signed-off-by: Kent Overstreet

drivers/md/bcache/extents.c: use %zi to format size_t

2014-02-11T00:01:40Z

drivers/md/bcache/extents.c: In function `btree_ptr_bad_expensive': drivers/md/bcache/extents.c:196: warning: format `%li' expects type `long int', but argument 4 has type `size_t' Signed-off-by: Geert Uytterhoeven Cc: Kent Overstreet Cc: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

bcache: Add bch_bkey_equal_header()

2014-01-08T21:05:14Z

Checks if two keys have equivalent header fields. (good enough for replacement or merging) Used in bch_bkey_try_merge, and replacing a key in the btree. Signed-off-by: Nicholas Swenson Signed-off-by: Kent Overstreet

bcache: update bch_bkey_try_merge

2014-01-08T21:05:14Z

Added generic header checks to bch_bkey_try_merge, which then calls the bkey specific function Removed extraneous checks from bch_extent_merge Signed-off-by: Nicholas Swenson

bcache: Move insert_fixup() to btree_keys_ops

2014-01-08T21:05:14Z

Now handling overlapping extents/keys is a method that's specific to what the btree node contains. Signed-off-by: Kent Overstreet

bcache: Convert debug code to btree_keys

2014-01-08T21:05:13Z

More work to disentangle various code from struct btree Signed-off-by: Kent Overstreet

bcache: Add struct btree_keys

2014-01-08T21:05:13Z

Soon, bset.c won't need to depend on struct btree. Signed-off-by: Kent Overstreet
