2014-08-04	bcache: Fix a journal replay bug	Kent Overstreet	1	-4/+9
	journal replay wansn't validating pointers with bch_extent_invalid() before derefing, fixed Signed-off-by: Kent Overstreet <kmo@daterainc.com>
2014-03-18	bcache: remove nested function usage	John Sheu	1	-9/+13
	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 <john.sheu@gmail.com>
2014-03-18	bcache: Kill bucket->gc_gen	Kent Overstreet	1	-4/+4
	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 <kmo@daterainc.com>
2014-03-18	bcache: Add a real GC_MARK_RECLAIMABLE	Kent Overstreet	1	-3/+3
	This means the garbage collection code can better check for data and metadata pointers to the same buckets. Signed-off-by: Kent Overstreet <kmo@daterainc.com>
2014-02-10	drivers/md/bcache/extents.c: use %zi to format size_t	Geert Uytterhoeven	1	-1/+1
	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 <geert@linux-m68k.org> Cc: Kent Overstreet <kmo@daterainc.com> Cc: Neil Brown <neilb@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2014-01-08	bcache: Add bch_bkey_equal_header()	Nicholas Swenson	1	-2/+1
	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 <nks@daterainc.com> Signed-off-by: Kent Overstreet <kmo@daterainc.com>
2014-01-08	bcache: update bch_bkey_try_merge	Nicholas Swenson	1	-5/+0
	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 <nks@daterainc.com>
2014-01-08	bcache: Move insert_fixup() to btree_keys_ops	Kent Overstreet	1	-0/+178
	Now handling overlapping extents/keys is a method that's specific to what the btree node contains. Signed-off-by: Kent Overstreet <kmo@daterainc.com>
2014-01-08	bcache: Convert debug code to btree_keys	Kent Overstreet	1	-4/+89
	More work to disentangle various code from struct btree Signed-off-by: Kent Overstreet <kmo@daterainc.com>
2014-01-08	bcache: Add struct btree_keys	Kent Overstreet	1	-7/+12
	Soon, bset.c won't need to depend on struct btree. Signed-off-by: Kent Overstreet <kmo@daterainc.com>
2014-01-08	bcache: Abstract out stuff needed for sorting	Kent Overstreet	1	-0/+354
	Signed-off-by: Kent Overstreet <kmo@daterainc.com>
