[LTP] LTP tests for fallocate

[Sharyathi N. <sha...@in...>]

Hi
   I am attaching a test cases written for testing fallocate() system 
call. Please go through the tests and let us know of your opinion.
   A few points I wanted to put forth.
o It needs to be executed from a folder that has EXT4 partition.
	else it will come out with error
o __NR_FALLOCATE needs to be declared under 	
                     include/linux_syscall_numbers.h
Some of the architecture specific values:
x86 		324
x86_64 		324
ia64		1303
s390		314

Thanks
