o bugfix
- bugfix: support complex whiteout/diropq case, when an existed upper
entry is not a directory, skip the test for diropq, reported by
Michael Towers.
- bugfix: a race condtion between UDBA and aufs.
+ check inode generation too
+ update file generation too
+ merge updating generations of dentry and inode, remove
hin_iigen(), rename hin_digen_tree() to hin_gen_tree(), rename
hin_digen_by_inode() to hin_gen_by_inode(), rename
hin_digen_by_name() to hin_gen_by_name().
+ use the flag in sbinfo to represent UDBA occured.
+ new function hin_attr() to support fuse.
+ use big aufs write lock in postproc(). this is the biggest change.
+ add a flag for big aufs write lock.
o news
- new sample for VMware and aufs.
- a new configuration CONFIG_AUFS_SHWH and new options shwh/noshwh
(still testing).
+ add some parameters to nhash_append_wh().
+ add some members to struct aufs_wh.
+ new function au_shwh_init_wh().
+ pass the latest mount flags to au_opts_parse().
+ print it in /proc/mounts.
+ new function au_flag_test_shwh().
+ extract a function au_ino() from fillvdir().
+ new functions au_wh_ino() and au_handle_shwh().
- tested on 64bit environment.
- support plink option at exporting via NFS.
- support huge number of pseudo-links.
o misc
- reduce #ifdef in source files.
+ define an empty AuNoNfsBranchMsg macro.
+ new functions au_test_nested() and au_test_unsupported_nfs()
+ a new function au_test_inotify()
- remove unnecessary alignment attribute for struct rename_args.
- remove unnecessary au_iigen_inc().
- new entry under sysfs for debugging.
