Btrfs-progs test case 023 will cause assert and a lot of false alerts
for lowmem mode.
The problems are caused by several reasons, from bad handler for tree
reloc root(calling btrfs_read_fs_root on tree reloc tree) to too
restrict check.
Fix the lowmem mode bugs.
There is another bug which affects both original mode and lowmem mode,
it seems to be caused by this commit:
commit 00e769d04c2c83029d6c71fbded133597d93ad55
Author: Goldwyn Rodrigues <rgold...@suse.com>

btrfs-progs: Correct value printed by assertions/BUG_ON/WARN_ON
Informed Goldwyn to fix it.
So the fix for the common assert is not included in this patchset.
Qu Wenruo (4):
btrfs-progs: check: Fix assert when using lowmem on fs with tree reloc
tree
btrfs-progs: check: Fix lowmem mode stack overflow caused by fsck/023
btrfs-progs: check: Fix lowmem false alert on tree reloc tree
btrfs-progs: check: Fix false alert on generation mismatch for tree
reloc tree
