Move the whole code dealing with parsing threads at collect_pstree stage into one function. The nr_threads calculation is performed inside it based on the amount of directories in /proc/pid/task, not the Threads: count in status. Error from xrealloc is ignored by now. Signed-off-by:

sigactions are restored before memory and if a parent get a signal which has a handler, it will get segmentation fault. This problem will disappear, when we add a freezer, because all processes will be resumed after restoring. Signed-off-by:

A file destriptor is opened for read-only and mmap with PROT_WRITE fails. We don't need PROT_WRITE for this case, because a file contains up to date data. lr-x------ 1 root root 64 Dec 1 19:10 20 -> /usr/lib64/gconv/gconv-modules.cache pos: 0 flags: 0100000 41155 mmap(0x7f2c3d6cf000, 28672, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_FIXED, 20, 0 <unfinished ...> 41155 <... mmap resumed> ) = -1 EACCES (Permission denied) Signed-off-by:

It's because this mask will be restored as rt_sigframe->uc.uc_sigmask. uc_sigmask will be set as current->blocked in sigreturn, so we should dump SigBlk in this case. Signed-off-by:

Reduce the pages-xxx.img file size significantly (from 2.1M to ~100K for simple counter test) by not dumping private file pages, that have not yet changed from its file prototype. If you'll have problems with it, just let me know and comment the definition of PAGE_ANON not to block your work. This uses the implemented earlier flag from mincore. Signed-off-by:
