Linus Torvalds ae67d9a888 New features for 3.12: ... * Added aggressive extent caching using the extent status tree. This can actually decrease memory usage in read-mostly workloads since the information is much more compactly stored in the extent status tree than if we had to keep the extent tree metadata blocks in the buffer cache. This also improves Asynchronous I/O since it is it makes much less likely that we need to do metadata I/O to lookup the extent tree information. * Improve the recovery after corrupted allocation bitmaps are found when running in errors=ignore mode. Also fixed some writeback vs. truncate races when using a blocksize less than the page size. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAABCAAGBQJSJ1SxAAoJENNvdpvBGATw6xAP/250u0YggRHup5cxmkJ7x+EH sv/Kbe8r1ftUY7aBQP1awHlVYnOZehh+kYUj+eIVPPXKananhu99qcJy99KFm8W9 gWVP5G0+zvKD++S8yHKhyKjqUtzZwhlYJU7oyqptPr903CVlfjsKx1OtGvUlbnde Hh/e+XpbltICPIa/O6gsE3SyRakbPtI0gvC4GbsD6EvAl+Rj3l6l+Ty9IkDqGFs9 YCVA2MUly6ZFYNRS8wkOPRP8T8lLwqIa7CNc75bEJPrGQL1R0iiIez0yaoZ83SOu HMC6wo3XjfgcsuMwJo/mtYsw06rjQy5oNPD5bISRaDtocI5v5Rv8t5EmANnoJFbu gy+psJ0XcKimL1BfsQ4vFCNiAkskkCQaFr2yJbo6VTDtHS8XV39MeMZ6IvcSqO+6 DQafMcKNiltDbdsywncsee+8ecncv/ZEZDiA6pIUm0lbljPopuzf6sBvxWOFGiHM xMBD0eyhns/TzfYHzzI+fTcR+GdBDqAkNOrA9i4medffS6iJDAJ6qC6ZhgQh32oR MCfYosVQwxmCInqtCh51+od29rk7ZIuBrPjp1+uMHjHqG5jDKcANgB7g3VAeQOf0 zuEYTFvGk6cLKfuJtlnaItKXN+eRTtVtfHlLRRq1+wR9UK+dFONV0Jufzs7Y1URI LbsmGkgxTL9xZEskZXgQ =tosu -----END PGP SIGNATURE----- Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4 Pull ext4 updates from Ted Ts'o: "New features for 3.12: - Added aggressive extent caching using the extent status tree.
