Many tests claimed (via _supported_os) to work on both Linux and IRIX. Since IRIX is no longer supported by xfstests, update these to claim Linux support only. Then remove any obvious IRIX-specific logic in the tests, and any IRIX-specific golden output files.

# FS QA Test 118
|
|
#
|
|
# Test xfs_fsr's handling of 2-extent files with preallocation
|
|
#
|
|
# An error in xfs_swap_extent_forks() incorrectly set up the
|
|
# temporary inode's if_extents pointer to inline, leading to
|
|
# in-memory corruption when the temporary inode was released
|
|
# and torn down; i_itemp and d_ops got overwritten with zeros,
|
|
# which led to an oops in xfs_trans_log_inode down the fput path.
|
|
#
|
|
# Fixed upstream by proper nextents counting using
|
|
# ip->i_df.if_bytes not ip->i_d.di_nextents in xfs_swap_extent_forks
