Okajima <hooanon05@yahoo.co.jp> Date: Wed Mar 2 13:34:55 2011 +0900 aufs: refine a mutex for mmap 2/3, replace lockdep_off by dep_map Since it can hide an important debug message, calling lockdep_off/on is a bad approach. But aufs_mmap() does it in switching the owner of fi_mmap mutex lock. Delegating a top-half of aufs_mmap() and switching the owner of fi_mmap is still an ugly approach, but I don't find another way. Without lockdep_off, the kernel debugging feature produces a false message. Stop calling lockdep_off/on, use lockdep_acquire/release instead thus we can get benefit from the debugging feature. This is slightly tricky and a feature for debugging only. Signed-off-by: J. R. Okajima <hooanon05@yahoo.co.jp> commit dcdfe3b9d0e67b2a9636813d452159495d205e92 Author: J. R.

During in this mode, /sbin/mount.aufs exec(2) the original mount(8). If mount(8) is not statically linked, it may mmap(2) ld.so (and others). And if ld.so is inside of the target aufs, then aufs mmap(2) blocks, ie. deadlock. To address this problem, specify O_CLOEXEC for /proc/fs/aufs/plink_maint which makes aufs to exit the plink maintenance mode, and ->release() doesn't care about pid.

In order to support such filesystem, old aufs1 follows it if h_dentry is dropped without d_instantiate(). Recently I looked whether there still exists such filesystem or not, and could not find. So aufs_link() uncondionally calls d_instantiate() after success of vfs_link() for branch fs. But, as a fallback, d_drop() call with a d_unhashed() test are left. Signed-off-by: J. R.

In this refreshing, objects for a dir and non-dir are separatedly handled for performance. This commit forces always refreshing both.

Also they may be in freeing, so call dget_locked() instead of simple dget(). The permission of the branch who has the negative dentry may be changed to readonly, so confirm it in au_pin_and_icpup().

For allocating inodes, VFS calls s_op->alloc_inode() and then adds it to s_inodes. Also for destroying, VFS removes it from s_inodes first and then calls s_op->destory_inode(). With this sequence, it is guranteed that the inode in s_inodes is always correct and we can refer struct au_iinfo. But for files, VFS adds the file object to s_files before calling f_op->open(), and calls ->release() before removing it from s_files. It means the file in s_files MAY be incorrect and we may not refer struct au_finfo. To support the file which is not initialized yet, aufs tests file->private_data. And to address the file which is released but still in s_files, aufs removes it from s_files first in file release operation. Signed-off-by: J. R.
