o news
- new scheme to pin the hierarchy on lower branch (introduced in last
Monday release) is still in testing phase. after its completions, the
fix will be backported to fs/aufs (linux-2.6.24 and earlier).
- some other bugfixes are made in this release. they will be backported
to fs/aufs too when I have time.
o bugfix
- bugfix (fs/aufs25 only, currently): pin the hierarchy on lower branch
and new ignore scheme for inotify (still testing).
+ add a prefix 'au_' to struct link_args, cpup_before_link() and
cpup_or_link().
+ aufs_link() allocates some large variables dynamically.
+ au_do_pin() never returns until all locks and verifications are
completed.
+ call au_pin() from lock_hdir_create_wh() instead of several manual
lockings.
+ call au_pin utility functions from aufs_unlink() and aufs_rmdir().
+ call di_downgrade_lock() from aufs_write(), aufs_splice_write(),
aufs_mmap() and aufs_fsync_nondir().
+ make au_do_unpin() global.
+ make au_pin_gp() as CONFIG_AUFS_HINOTIFY local.
+ move au_unpin() from i_op.c to inode.h and make it inlined.
+ move au_unpin_gp() from i_op.c to hinotify.c.
+ new inline functions au_pin_do_set_parent_lflag(),
au_pin_set_parent_lflag() and au_pin_set_gparent_lflag().
+ refine au_cpup_before_link() by using au_pin/unpin().
+ rename lsc_i to lsc_hi.
+ remove some parameters frome rename functions by passing struct
au_ren_args.
+ rename struct rename_args to au_ren_args, add some members to reduce
the stack size.
+ simplify aufs_d_revalidate() by write_lock + downgrade_lock.
+ simplify au_hi_lock() by removing some parameters.
+ simplify do_coo() and au_ready_to_write() by removing some
variables.
+ simplify lock_hdir_create_wh(), aufs_unlink() and aufs_rmdir() by
removing some variables.
+ simplify lock_hdir_lkup_wh(), add_simple(), struct au_link_args,
au_cpup_or_link() and aufs_mkdir() by removing some variables.
+ simplify struct au_icpup_args, au_lock_and_icpup() and
aufs_setattr() by removing/adding some members.
+ split do_rename() into some small functions.
- bugfix (fs/aufs25 only, currently): lock child dentry first in
aufs_lookup(), and unlock the parent as soon as possible.
this fix will be backported to fs/aufs too.
- bugfix (fs/aufs25 only, currently): stop locking child inode in
reval_inode().
this fix will be backported to fs/aufs too.
- bugfix (fs/aufs25 only, currently): revert the timestamps of the
parent dir at flushing pseudo-links.
this fix will be backported to fs/aufs too.
o misc
- declare copyright 2005-2008 in all files, because I was told it should
be done per software instead of per file even in the files which I
didn't change this year.
- enhancement for CONFIG_4KSTACKS, allocate a large structure
dynamically in au_wkq_run() instead of stack.
- minor optimization, use unsigned long long pointer for testing a hole
in a file.
- call kzalloc() instead of kmalloc() + memset(,0,).
- unset noinline_for_stack to epilog(), lock_hdir_lkup_wh() and
au_cpup_or_link().
- unset noinline_for_stack to cpup_regular() and au_do_cpup_regular().
- unset noinline_for_stack to decode_by_dir_ino().
- reduce the stack size.
