Re: corruption on my ext2fs with 2.4.0-test10

[Mircea Damian <dmircea@linux.kappa.ro>]

OK, problem found.
Something is broken (I've tested on a new 2.4.0-test12-pre3). Look here:

If I run strace through the perl script I get something like:

root@invasion:/usr/src/archives/perl-5.6.0/t# strace ./perl op/lfs.t
...
open("big", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0
fcntl(3, F_SETFD, FD_CLOEXEC)           = 0
fstat(3, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0
old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40015000
_llseek(3, 5000000000, [5000000000], SEEK_SET) = 0
write(3, "big", 3)                      = 3
close(3)                                = 0
munmap(0x40015000, 4096)                = 0
stat("big", 0xbffff980)                 = -1 EOVERFLOW (Value too large for defined data type)
...

I believe that _llseek() call should return EINVAL. Right?
