The watch target might be a deleted file. In this case we can't re-create it on restore procedure. A typical scenario ------------------ fd = inotify_init1() wd = open(path) inotify_add_watch(path) unlink(path) ... checkpoint ... here we have a @path which is unlinked but still present in inotify watch list because inode is not yet freed. And if the program is killed after checkpoint the last reference to a path get eliminated and inode get freed from the kernel memory. Thus any furher attempts to open the path via file handle (note that file handle can't be used to create new file, the kernel doesn't permit that) will simply fail. So if plain opening via file handle failed we assume that at least the file might be in our ghost files list (we're optimists, right?) and if we successed we simply use a path generated by ghost file engine for us. v2 [by xemul@]: - gather reference to ghost file remap early Signed-off-by:

Because we need to lookup for ghost files from inotify system where we only have device/inode as a key, we save dev/ino in ghost image entry. Note we use in-kernel format for device to be consistent with inotify and mount related code base. Signed-off-by:

The remap_put will be needed to defer unlinking of ghost files if they are referred from inotify system. The lookup_remap is needed to figure out if the watch target the inotify has present in ghost files list. Signed-off-by:

A value of signo is in [1, SIGMAX]. Currenly signals are enumirated from 1 to SIGMAX, but SIGMAX is not included. This patch fixes this mestake. v2: * save backward compatibility * set a correct value of SIGMAX = 64. It can not be in a separate patch, because a format is changed again.

Switching to a new stage is 4-step procedure which deserves its own helper. Besides, now the information about how many tasks participage in each stage is collected in one place. Signed-off-by: -

When finishing a stage we have to report this (decrement the number of tasks in stage) and wait while stage switch. Write a helper that does both. Signed-off-by: -

Otherwise test with -d option get fail (this is because SIGTRAP get cleared by our parasizte engine). The proper fix most likely will require kernel patching or redesign of parasite code. Meanwhile to make test working we switch to the signal which just known to work. Reported-by:
