o bugfix
- bugfix: set PINNED flag unconditionally in au_ren_pin(), regression on
20081020.
- bugfix: re-initialize gparent array explicitly in au_ren_pin().
- bugfix: in robr mode, support the multi-threaded library call,
reported by Julien Bonjean.
- bugfix: support freeing inodes at anytime, reported by Stefanik Gabor.
- bugfix: in linux-2.6.27 and later, some LSM doesn't support some MAY_
bits and need to drop them before calling security_inode_permission(),
reported by "fd".
- bugfix: mis-used the filename variable $f.
- bugfix(still working): stop recursive si lock, reported by Louis
Rilling.
+ append a parameter au_decode for au_lkup_by_in(),
decode_by_dir_ino() and decode_by_path().
+ call au_hin_wq_init() and initialize a new member.
+ call generic au_dbg_{,un}reg() from au_dbg_[sdi]i_{,un}reg().
+ initialize a new member si_nfsd_pid.
+ make si lock functions wrapping new debug functions and to call
au_nfsd_test_si_lock().
+ new functions au_decode_{,un}lock().
+ new functions au_hin_wq_{init,wake}().
+ new functions si_nfsd_pid_{,un}reg().
+ a new function au_nfsd_test_si_lock().
+ new members si_hin_wq and si_nfsd_pid.
+ new structure au_decode.
+ a new structure au_nfsd_pid.
+ print lock informations in sysrq_sb().
+ remove lockdep_{on,off}().
+ rename the prefix of si lock functions to si_do_.
+ replace si write_lock() call in postproc() by
wait_event(si write_trylock()).
+ replace the structure au_dbg_lock_di by a new generic structure
au_dbg_lock.
o misc
- support PPC64 (or PPC) which doesn't export the symbol empty_zero_page
in linux-2.6.25 (untested).
- add a debug feature for si/ii lock.
+ new enumerators AuDbgLock_[SI]I_LOCK{ING,ED}.
+ new debug functions au_dbg_lock{ing,ed}_[si]i_{,un}reg().
+ call new debug functions au_dbg_lock{ing,ed}_ii_{,un}reg().
+ call new debug function au_dbg_locked_si_reg().
- remove many unlikely() macros in order to improve the cpu usage, but
it doesn't mean that aufs runs faster.
- minor enhancement: remove the temporary files when an error happened.
- minor enhancement: detect the remount flag earlier.
