* btrfs-progs: qgroup: Fix regression leads to corrupted qgroup statusQu Wenruo2016-10-03
| | | | | | | | | | | | | | | | | | | | | | | Commit 93dabf211d74daf6e3de642bdd887a90a00f7b49 Author: Mark Fasheh <mfasheh@suse.de> Date: Fri Jun 17 13:37:48 2016 -0700 btrfs-progs: check: verify qgroups above level 0 This commit introduced a new regression which corrupts read_qgroup_status, since it iterate leaf with manually specified slot, not correct path->slot[0]. This leads to wrong slot[0] and read_qgroup_status() will read out wrong flags, leading to regression. Fix read_qgroup_status() by using eb and slot instread of wrong path strucutre.

* btrfs-progs: super-recover: Reuse btrfs_read_dev_super functionQu Wenruo2016-10-03
| | | | | | | | | | | | We have enhanced super block validation check in disk_io.c, while super-recover doesn't use that function and use a custom one. That is duplicated, so reuse btrfs_read_dev_super to handle it, which not only enhanced super check, but also reduce the code length.

* btrfs-progs: Return more meaningful value for btrfs_read_deve_superQu Wenruo2016-10-03
| | | | | | | | | | | | | | btrfs_read_dev_super() only returns 0 or -1, which doesn't really help, caller won't know if it's caused by bad superblock or superblock out of range. Return -errno if pread64() return -1, and return -EOF if none or part of the super is read out, and return what check_super() returned. So caller can get -EIO to catch real corrupted super blocks.
