Dump SigBlk instead of SigCgt · 75536202

Andrey Vagin authored Nov 29, 2011

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.

crtools: Take MINCORE_ANON pages into account · bb3d02c2

Pavel Emelyanov authored Nov 25, 2011

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.
