17
- two bugfixes(pinning and dlgt) and local tests for them are completed.
18
- bugfix (fs/aufs25 only, currently): pin the hierarchy on lower branch
19
and new ignore scheme for inotify (completed).
20
+ adjust the lock subclass in au_ren_pin_init().
21
+ change the dinfo lock subclass in au_test_and_cpup_dirs() from
23
+ change the lock subclass from AuLsc_I_PARENT2 to AuLsc_I_CHILD.
24
+ change the lock subclass from AuLsc_I_PARENT to AuLsc_I_CHILD.
25
+ change the name of a lock subclass NEW to NEW_CHILD.
26
+ do not set inotify for whiteouted dirs (SHWH mode).
27
+ ignore a dead child dentry.
28
+ ignoring inotify events for creating/removing the default xino
29
files, introduce new member si_xino_def_br.
30
* reset si_xino_def_br when the removed branch is added again in
32
* unset si_xino_def_br when the branch is deleted in au_br_del().
33
+ ignore the old whiteout when it was moved.
34
+ initialize dinfo lock by AuLsc_DI_CHILD instead of AuLsc_DI_PARENT.
35
+ lock iinfo in xino_do_trunc().
36
+ make the type of au_pin() and au_do_pin() void. this fix may be
37
reverted since a tiny bug can cause a deadlock.
38
+ remove a function au_hi_lock().
39
+ remove a member unpinned from struct au_link_args.
40
+ remove a parameter parent from au_xino_create().
41
+ remove dlgt test in au_wkq_run(), with this fix the fix for dlgt is
43
+ replace the inode lock subclass AuLsc_I_PARENT2 by AuLsc_I_CHILD in
45
+ restore the function au_hin_resume().
46
+ revert the inotify watch when an error occured.
47
+ set ignore info at re-initializing whiteout for a branch.
48
+ set ignore info in an error case in au_do_cpup_regular().
49
+ set noinline_for_stack to cpup_regular() and au_do_cpup_regular().
50
+ simplify vfsub_create(), vfsub_symlink(), vfsub_mknod(),
51
vfsub_mkdir(), vfsub_link(), vfsub_rename(), vfsub_rmdir(),
52
vfsub_write_k() and vfsub_splice_from().
53
+ switch the inode lock subclass in au_cp_dirs(), AuLsc_I_PARENT2 and
55
+ verify the child-parent relationship in call_rmdir_whtmp().
56
- bugfix: replace "${TgtPath}/Kconfig" by "aufs/Kconfig", reported and
57
patched by Paulius Zaleckas.
58
- bugfix: prepend CONFIG_ to ccflags-$(AUFS_WORKAROUND_FUSE).
59
- minor optimization: compare the read buffer with a zeroed page to
60
detect a hole in a file. this may be reverted in the future since this
61
optimization consumes one memory page.
62
- minor optimization in is_sb_shared().
63
- replace MmTree macro by CONFIG_AUFS_UNIONFS22_PATCH and
64
CONFIG_AUFS_UNIONFS23_PATCH.
65
- remove MmTree macro.
66
- kmalloc() some large structures in au_dpri_sb() (completed).
67
+ replace GFP_NOFS by GFP_ATOMIC.
70
- new scheme to pin the hierarchy on lower branch (introduced in last
71
Monday release) is still in testing phase. after its completions, the
72
fix will be backported to fs/aufs (linux-2.6.24 and earlier).
73
- some other bugfixes are made in this release. they will be backported
74
to fs/aufs too when I have time.
75
- bugfix (fs/aufs25 only, currently): pin the hierarchy on lower branch
76
and new ignore scheme for inotify (still testing).
77
+ add a prefix 'au_' to struct link_args, cpup_before_link() and
79
+ aufs_link() allocates some large variables dynamically.
80
+ au_do_pin() never returns until all locks and verifications are
82
+ call au_pin() from lock_hdir_create_wh() instead of several manual
84
+ call au_pin utility functions from aufs_unlink() and aufs_rmdir().
85
+ call di_downgrade_lock() from aufs_write(), aufs_splice_write(),
86
aufs_mmap() and aufs_fsync_nondir().
87
+ make au_do_unpin() global.
88
+ make au_pin_gp() as CONFIG_AUFS_HINOTIFY local.
89
+ move au_unpin() from i_op.c to inode.h and make it inlined.
90
+ move au_unpin_gp() from i_op.c to hinotify.c.
91
+ new inline functions au_pin_do_set_parent_lflag(),
92
au_pin_set_parent_lflag() and au_pin_set_gparent_lflag().
93
+ refine au_cpup_before_link() by using au_pin/unpin().
94
+ rename lsc_i to lsc_hi.
95
+ remove some parameters frome rename functions by passing struct
97
+ rename struct rename_args to au_ren_args, add some members to reduce
99
+ simplify aufs_d_revalidate() by write_lock + downgrade_lock.
100
+ simplify au_hi_lock() by removing some parameters.
101
+ simplify do_coo() and au_ready_to_write() by removing some
103
+ simplify lock_hdir_create_wh(), aufs_unlink() and aufs_rmdir() by
104
removing some variables.
105
+ simplify lock_hdir_lkup_wh(), add_simple(), struct au_link_args,
106
au_cpup_or_link() and aufs_mkdir() by removing some variables.
107
+ simplify struct au_icpup_args, au_lock_and_icpup() and
108
aufs_setattr() by removing/adding some members.
109
+ split do_rename() into some small functions.
110
- bugfix (fs/aufs25 only, currently): lock child dentry first in
111
aufs_lookup(), and unlock the parent as soon as possible.
112
this fix will be backported to fs/aufs too.
113
- bugfix (fs/aufs25 only, currently): stop locking child inode in
115
this fix will be backported to fs/aufs too.
116
- bugfix (fs/aufs25 only, currently): revert the timestamps of the
117
parent dir at flushing pseudo-links.
118
this fix will be backported to fs/aufs too.
119
- declare copyright 2005-2008 in all files, because I was told it should
120
be done per software instead of per file even in the files which I
121
didn't change this year.
122
- enhancement for CONFIG_4KSTACKS, allocate a large structure
123
dynamically in au_wkq_run() instead of stack.
124
- minor optimization, use unsigned long long pointer for testing a hole
126
- call kzalloc() instead of kmalloc() + memset(,0,).
127
- unset noinline_for_stack to epilog(), lock_hdir_lkup_wh() and
129
- unset noinline_for_stack to cpup_regular() and au_do_cpup_regular().
130
- unset noinline_for_stack to decode_by_dir_ino().
131
- reduce the stack size.
134
- bugfix (fs/aufs25 only, currently): pin the hierarchy on lower branch
135
and new ignore scheme for inotify (still debugging).
136
under heavy i/o (including rename(2)), aufs may misunderstand
137
the child-parent relationship. new structure au_pin locks both parent-
138
child and verifies them.
139
additionally, when udba=inotify is specified, aufs sets inotify watch
140
internally for the parent (and grand parent) dir in cache, and ignores
141
the events triggered by aufs internal activity. this was done by
142
locking the lower dir and setting 0 to the event mask for the lower
143
dir, but it might ignore the event fired by other process, for example
144
write(2) to the lower file.
145
the new method stops setting 0 to the mask, and ignores the event made
147
this fix is not backported to fs/aufs yet since it is still
148
debugging. so the old behaviour is taken on the older kernels.
149
people will call it crazy due to many locks.

159
cpup_iattr(), and set ignore info.

174
+ append a new lock subclass id AuLsc_DI_PARENT4.
175
+ append a new lock subclass id AuLsc_I_(PARENT|CHILD)[34].
176

178
aufs_mmap(), aufs_poll(), aufs_fsync_nondir() and aufs_fasync()
179
unlock both dinfo and iinfo.
