2.6.30-stable review patch. If anyone has any objections, please let us know. ------------------ From: Dave Kleikamp commit f7c52fd17a7dda42fc9e88c2b2678403419bfe63 upstream. Commit fec1878fe952b994125a3be7c94b1322db586f3b caused a regression in which contiguous blocks being allocated to the end of an extent were getting a new extent created. This typically results in files entirely made up of 1-block extents even though the blocks are contiguous on disk. Apparently grub doesn't handle a jfs file being fragmented into too many extents, since it refuses to boot a kernel from jfs that was created by the 2.6.30 kernel.
