Commit 7a7641063a (xfs/140: work with 64k
block size) created a test filesystem with AG size set to (8192 * block
size). When working with a 1k block sized XFS filesystem, this tries to
set the AG size to 8MiB which is less than the minimum AG size of
16MiB. Hence creation of the filesystem had actually failed.
This commit fixes the issue by resetting AG size to 16MiB if (8192 *
block size) results in a value less than 16MiB. Later the test file size
and the test file block count are then appropriately calculated.

On a 64k blocksized filesystem, when the test CoWs the file2's offset
range [10 * 64k, 19 * 64k], the call to xfs_bmapi_reserve_delalloc()
allocates 32 64k blocks. This is because XFS_DEFAULT_COWEXTSZ_HINT has
the value of 32 and xfs_get_cowextsz_hint() uses this to compute the
extent alignment. This leads to xfs_bmapi_reserve_delalloc() to reserve
space corresponding to the file range [0, 32 * 64k] in the inode's
cow fork area. On completion of write I/O corresponding to file2's range
[10 * 64k, 19 * 64k], xfs_end_io() moves 10 out of the originally
allocated 32 64k blocks to the data fork area. The remaining 22 64k
blocks linger on in cow fork area of the inode.
Later, when servicing the exit() syscall for the xfs_io process,
xfs_free_eofblocks() ends up invoking xfs_reflink_cancel_cow_blocks()
since i_delayed_blks has the value 22. xfs_reflink_cancel_cow_blocks()
indirectly invokes __xfs_free_extent() which returns EIO since
XFS_ERRTAG_FREE_EXTENT has been set. This leads to the filesystem to be
shutdown. The "rm" command invoked later ends up returning an
error and hence the test fails. The test actually requires that the
filesystem gets shutdown when executing the "rm" command.
To fix the problem, this commit injects the free_extent error after we
CoW file2's [10 * 64k, 19 * 64k] range.

14 test cases use _test_generic_punch(), and they work well as long
as the ext4/xfs blocksize or btrfs sectorsize is below 4K.
In the system with 64K pagesize, as the blocksize can be upto 64K or the
sectorsize can be 64K so 13/14 test cases fail, because the
test-file-size (20k) and thus the extent boundary offsets aren't
big enough to fit the larger than 4k extent size.
Commit 2f194e4e82 (generic/009: don't run
for btrfs if PAGE_SIZE > 4096) tried to address this by calling the
not_run in generic/009.
And in the function _test_generic_punch() we use multiple=4 to address
the similar problem but its limited to the subcommand fcollapse.
Now to run these test cases successfully on systems with pagesize 64k,
this patch propose to increase the default multiple=1 to multiple=16.
With this we increase the test file size from 20k to 320k and thus it
encapsulates maximum extent size of 64k here. And we can drop the
multiple=4 which is just being done similar for the cases of fcollapse
subcommand only. And it appears to me there is no harm in increasing
the file size and offsets in general for all commands instead of just
fcollapse command.
This change is tested on ext4, xfs and btrfs on system with pagesize
4K and 64K.
With this patch, these 14 test cases runs fine on system with 64K
pagesize as well as pagesize 4K. However we may hit the same
limitation at some point when we want to validate the FSs with
pagesizes -gt 64K. And this patch does not address that part as of
now.
