xfs: calculate inode walk prefetch more carefully The existing inode walk prefetch is based on the old bulkstat code, which simply allocated 4 pages worth of memory and prefetched that many inobt records, regardless of however many inodes the caller requested. 65536 inodes is a lot to prefetch (~32M on x64, ~512M on arm64) so let's scale things down a little more intelligently based on the number of inodes requested, etc. Signed-off-by: Darrick J.
