At a 32 bit guest UML with current kernel git tree I putted a printk
into that function :
void truncate_inode_pages_range(struct address_space *mapping,
loff_t lstart, loff_t lend)
{
...
cond_resched();
index++;
printk (" <------------
and got (while fuzzying the UML guest with trinity) this output in the
UML guest:
Nov 24 12:06:53 trinity kernel: index:42 end:4294967295
Nov 24 12:06:53 trinity kernel: index:43 end:4294967295
Nov 24 12:06:53 trinity kernel: index:5 end:4294967295
Nov 24 12:06:53 trinity kernel: index:1 end:4294967295
Nov 24 12:06:53 trinity kernel: index:1 end:4294967295
Nov 24 12:06:53 trinity kernel: index:1035468800 end:4294967295
Nov 24 12:06:53 trinity kernel: index:1 end:4294967295
Nov 24 12:06:53 trinity kernel: index:1 end:4294967295

Nov 24 12:06:53 trinity kernel: index:16 end:4294967295
Nov 24 12:06:53 trinity kernel: index:1 end:4294967295
Nov 24 12:06:53 trinity kernel: index:4 end:4294967295
Nov 24 12:06:53 trinity kernel: index:2 end:4294967295
Nov 24 12:06:53 trinity kernel: index:1 end:4294967295
Nov 24 12:06:53 trinity kernel: index:4184867847 end:4294967295
Nov 24 12:06:53 trinity kernel: index:1 end:4294967295
Nov 24 12:06:53 trinity kernel: index:3 end:4294967295
Nov 24 12:06:53 trinity kernel: index:1727 end:4294967295
Nov 24 12:06:53 trinity kernel: index:1 end:4294967295
I'm wondering if index is expected to become sometimes so big.
