This fixes a scalability problem reported by Andi Kleen and Tim Chen; they were quite secretive about the precise nature of their workload, but they later admitted that it only showed up when they were using a large sparse file, so the amount of data I/O that was needed was close to zero. I'm not sure how realistic this is and it's only a regression if you consider changes made since 2.6.39 to be a "regression" vis-a-vis the policy regarding post-merge window bug fixes, but Linus agreed it was worth fixing, so I'm including it in this pull request. This also fixes the journalled quota mount options, which I accidentally broke while I was cleaning up the mount option handling. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQIcBAABCAAGBQJPjbs2AAoJENNvdpvBGATw/4UQAOMsxRlzbMnOAmohIBmesJiB nTPX41dNw0QCXstMFjvSyRbUJI0NZPGg6ZDhbtoQ/c42/izZOVNd7gh7QQYHRCt2 Oqh6WS159P04ixcAe8NgCm5B5AV/C5Er/vSOUZENBaBo430vvrZasifsyUgQnx+b PxXlYsfPVzaQVeSxCu/68OeiBRLcLwmKZ6MicOaWt9GCNoCsWzgU+/LNskYuscPI 841yQL6/BE7redU2E9qoEn/xjxx57hJOj2iiIAuqGPmNmRQqq3VtvTqNZHldNBLp Hz5mB3zSZsPg0uwvp+OxrnpP37NQCCn1L64UFIXxqGF47mcCYw7schAoGBtqwGQS neGUfkzG4beKk7kojyDawvnrrvVn4iCMaIkR1ZjzjPOk+QBPagckrS2nmuObbYzJ l4lmHq1v8nOh0clxqJPioNp5/Y13sbpEOY4tAa6sLpzKLKXF330RNuwwrKKHB7zo ZhCvSwVEjmxacgPCPhFJnR3fxtjoXWR8WvJs7H+gZB/QaC8hjEYw6xvvrkw8mAiS RNe3cYdYAz6kOJdtJrJaMzp/1CYdHydf+0WvNYCQ/d1poPr7uU5wQY61hdm2gFxh owsbVAOiEFjZWJHqrRRdcg2irTpINJTS3iRe4g/ltcvYzzRSeOcZNWvkKFspq3i8 EUMHRBxLzPMRa+gU6Unm =jb3f -----END PGP SIGNATURE----- Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4 Pull ext4 regression fixes from Ted Ts'o: "This fixes a scalability problem reported by Andi Kleen and Tim Chen; they were quite secretive about the precise nature of their workload, but they later admitted that it only showed up when they were using a large sparse file, so the amount of data I/O that was needed was close to zero.
