Subject: [PATCH 0/5] xfs refcount conversions
Date: Fri, 20 Oct 2017 14:07:53 +0300 [thread overview]
Message-ID: <1508497678-10508-1-git-send-email-elena.reshetova@intel.com> (raw)
Note: our previous thread didn't finish in any conclusion, so
I am resending this now (rebased at latest linux-next) to revive
the discussion. refcount_t is slowly becoming a standard for
refcounters and we would really like to make all conversions
done where it is applicable.
******
This series, for xfs, replaces atomic_t reference
counters with the new refcount_t type and API (see include/linux/refcount.h).
By doing this we prevent intentional or accidental
underflows or overflows that can lead to use-after-free vulnerabilities.
The patches are fully independent and can be cherry-picked separately.
If there are no objections to the patches, please merge them via respective trees.
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
