That doesn't look like related to the bkl removal.
In fact what I wonder is how we missed that before.
vfs_readdir() take the directory inode mutex
|
------- copy_to_user() takes the mm->mmap_sem
sys_unmap() takes mm->mmap_sem
|
------- reiserfs_file_release() takes inode mutex
The lock inversion can not happen as sys_getdents() can't be called
after the directory is closed.
I'm not sure what to do. Adding more people in Cc.
