- Fixed lfs3_alloc_cansyncgbmap ignoring known window changes.
Being able to just call lfs3_btree_cmp(b, b_p) would be nice, but this
ignores known window changes!
Fixed by comparing the on-disk encoding, which is heavy-handed, but
probably the safest approach.
lfs3_alloc_cansyncgbmap will probably never be on the stack hot-path,
and the added code is roughly one function call. The main cost is
CPU-cycles, but fortunately(?) that's not something we really care
about?
- Fixed lfs3_allocclaim accidentally returning lfs3_mdir_commit's return
value instead of the allocated block!
Probably caused by a copy-paste, resulted in lfs3_allocclaim returning
block 0, which is really not good!
- Fixed assert typo in lfs3_trv_open where we assert REVPERTURB in flags
instead of lfs3->flags.
