[ext2resize] Re: [Ext2-devel] current status of online resizing

[Glauber de O. C. <go...@br...>]

BTW, something I forgot to mention: I was using ext2resize 1.1.17 at
that time. 
1.1.19 worked fine, but I could not compile it on my system until I
changed the  definition of BLKGETSIZE64 at ext2_unix_io.c 

from

#define BLKGETSIZE64 _IOR(0x12,114,sizeof(unsigned long long))

to 

#define BLKGETSIZE64 _IOR(0x12,114,unsigned long long)

That was a quick fix, and I have no time to get a more detailed reason
about which impacts would it bring on other parts of the code . Does it 
make sense to you ?
