Subject: [PATCH 0/5] fs, xfs refcount conversions

v3:
 * fixed header file inclusion

Now when new refcount_t type and API are finally merged
(see include/linux/refcount.h), the following
patches convert various refcounters in the xfs susystem from atomic_t
to refcount_t. By doing this we prevent intentional or accidental
underflows or overflows that can led to use-after-free vulnerabilities.


Elena Reshetova (5):
  fs, xfs: convert xfs_bui_log_item.bui_refcount from atomic_t to
    refcount_t
  fs, xfs: convert xfs_efi_log_item.efi_refcount from atomic_t to
    refcount_t
  fs, xfs: convert xlog_ticket.t_ref from atomic_t to refcount_t
  fs, xfs: convert xfs_cui_log_item.cui_refcount from atomic_t to
    refcount_t
  fs, xfs: convert xfs_rui_log_item.rui_refcount from atomic_t to
    refcount_t
