Tim Chase cb08f06307 Perform whole-page page truncation for hole-punching under a range lock ... As an attempt to perform the page truncation more optimally, the hole-punching support added in 223df0161f truncated performed the operation in two steps: first, sub-page "stubs" were zeroed under the range lock in zfs_free_range() using the new zfs_zero_partial_page() function and then the whole pages were truncated within zfs_freesp(). This left a window of opportunity during which the full pages could be touched. This patch closes the window by moving the whole-page truncation into zfs_free_range() under the range lock.
