[XFS] fix filestreams on 32-bit boxes
xfs_filestream_mount() sets up an mru cache with:
err = xfs_mru_cache_create(&mp->m_filestream, lifetime, grp_count,
(xfs_mru_cache_free_func_t)xfs_fstrm_free_func);
but that cast is causing problems...
typedef void (*xfs_mru_cache_free_func_t)(unsigned long, void*);
but:
void xfs_fstrm_free_func( xfs_ino_t ino, fstrm_item_t *item)
so on a 32-bit box, it's casting (32, 32) args into (64, 32) and I assume
it's getting garbage for *item, which subsequently causes an explosion.
With this change the filestreams xfsqa tests don't oops on my 32-bit box.
