Many test cases use xfs_io -c 'falloc' but forgot to add
_require_xfs_io_command "falloc". This will fail the test case if we run
the test case on a file system without fallcoate support e.g. F2FS ZZ
While we believe that normal fallocate(mode = 0) is always supported on
Linux, it is not true. Fallocate is disabled in several implementations of
zoned block support for file systems because the pre-allocated region will
break the sequential writing rule.
Currently, several test cases unconditionally call fallocate(). Let's add
_require_xfs_io_command "falloc" to properly check the feature is supported
by a testing file system.
