des 2001/10/07 12:37:14 PDT Modified files: sys/fs/procfs procfs_vnops.c Log: In procfs_readdir(), when the directory being read was a process directory, the target process was being held locked during the uiomove() call. If the process calling readdir() was the same as the target process (for instance 'ls /proc/curproc/'), and uiomove() caused a page fault, the result would be a proc lock recursion. I have no idea how long this has been broken - possibly ever since pfind() was changed to lock the process it returns. Also replace the one and only call to procfs_findtextvp() with a direct test of td->td_proc->p_textvp.
