o news
- two bugfixes(pinning and dlgt) and local tests for them are completed.
o bugfix
- bugfix (fs/aufs25 only, currently): pin the hierarchy on lower branch
and new ignore scheme for inotify (completed).
+ adjust the lock subclass in au_ren_pin_init().
+ change the dinfo lock subclass in au_test_and_cpup_dirs() from
PARENT2 to PARENT.
+ change the lock subclass from AuLsc_I_PARENT2 to AuLsc_I_CHILD.
+ change the lock subclass from AuLsc_I_PARENT to AuLsc_I_CHILD.
+ change the name of a lock subclass NEW to NEW_CHILD.
+ do not set inotify for whiteouted dirs (SHWH mode).
+ ignore a dead child dentry.
+ ignoring inotify events for creating/removing the default xino
files, introduce new member si_xino_def_br.
* reset si_xino_def_br when the removed branch is added again in
au_br_add().
* unset si_xino_def_br when the branch is deleted in au_br_del().
+ ignore the old whiteout when it was moved.
+ initialize dinfo lock by AuLsc_DI_CHILD instead of AuLsc_DI_PARENT.
+ lock iinfo in xino_do_trunc().
+ make the type of au_pin() and au_do_pin() void. this fix may be
reverted since a tiny bug can cause a deadlock.
+ remove a function au_hi_lock().
+ remove a member unpinned from struct au_link_args.
+ remove a parameter parent from au_xino_create().
+ remove dlgt test in au_wkq_run(), with this fix the fix for dlgt is
completed too.
+ replace the inode lock subclass AuLsc_I_PARENT2 by AuLsc_I_CHILD in
au_whtmp_rmdir().
+ restore the function au_hin_resume().
+ revert the inotify watch when an error occured.
+ set ignore info at re-initializing whiteout for a branch.
+ set ignore info in an error case in au_do_cpup_regular().
+ set noinline_for_stack to cpup_regular() and au_do_cpup_regular().
+ simplify vfsub_create(), vfsub_symlink(), vfsub_mknod(),
vfsub_mkdir(), vfsub_link(), vfsub_rename(), vfsub_rmdir(),
vfsub_write_k() and vfsub_splice_from().
+ switch the inode lock subclass in au_cp_dirs(), AuLsc_I_PARENT2 and
AuLsc_I_PARENT.
+ verify the child-parent relationship in call_rmdir_whtmp().
- bugfix: replace "${TgtPath}/Kconfig" by "aufs/Kconfig", reported and
patched by Paulius Zaleckas.
- bugfix: prepend CONFIG_ to ccflags-$(AUFS_WORKAROUND_FUSE).
o misc
- minor optimization: compare the read buffer with a zeroed page to
detect a hole in a file. this may be reverted in the future since this
optimization consumes one memory page.
- minor optimization in is_sb_shared().
- replace MmTree macro by CONFIG_AUFS_UNIONFS22_PATCH and
CONFIG_AUFS_UNIONFS23_PATCH.
- remove MmTree macro.
- kmalloc() some large structures in au_dpri_sb() (completed).
+ replace GFP_NOFS by GFP_ATOMIC.
