[PATCH] xfs: destroy mutex qi_tree_lock before free xfs_quotainfo_t object

The mutex qi_tree_lock of xfs_quotainfo_t object was initialized when calling xfs_qm_init_quotainfo, but it was not destroyed before free xfs_quotainfo_t object when calling xfs_qm_destroy_quotainfo, this was incorrect, so destroy it in function xfs_qm_destroy_quotainfo. Signed-off-by: Xiongwei

[PATCH] x86: xen: remove the use of VLAIS

Variable Length Arrays In Structs (VLAIS) is not supported by Clang, and frowned upon by others. https://lkml.org/lkml/2013/9/23/500 Here, the VLAIS was used because the size of the bitmap returned from xen_mc_entry() depended on possibly (based on kernel configuration) runtime sized data.
