Description of problem:
In calculating the amount of disk space for a dump, savecore uses the f_bavail
field from statfs. Since this does not include reserved blocks a savecore can
fail despite there being sufficient space in the dump file system.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Configure a /var/crash filesystem that is just large enough to contain system RAM
2. Perform a crash, e.g. sysrq-c
3. Wait for reboot to save core
"no space for dump image."
Dump copies succesfuly
