In ext3/4 some of the summary statistics for # of free\ninodes, blocks, and directories are calculated from the per-block\ngroup statistics when the file system is mounted or unmounted. As a\nresult the superblock doesn\u0027t have to be updated, either via the\njournal or by setting s_dirt. There are a few exceptions, most\nnotably when resizing the file system, where the superblock needs to\nbe modified --- and in that case it should be done as a journalled\noperation if possible, and s_dirt set only in no-journal mode.\n\nThis patch will optimize out some unneeded disk writes when using ext4\nwith a journal.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "84a8dce2710cc425089a2b92acc354d4fbb5788d", "tree": "2d83f638d52326b6a8080a26aa1423fa28b38ff1", "parents": [ "1f5a81e41f8b1a782c68d3843e9ec1bfaadf7d72" ], "author": { "name": "Dmitry Monakhov", "email": "dmonakhov@openvz.org", "time": "Sat Jun 05 11:51:27 2010 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Sat Jun 05 11:51:27 2010 -0400" }, "message": "ext4: Fix remaining racy updates of EXT4_I(inode)-\u003ei_flags\n\nA few functions were still modifying i_flags in a racy manner.\n\nSigned-off-by: Dmitry Monakhov \u003cdmonakhov@openvz.org\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "1f5a81e41f8b1a782c68d3843e9ec1bfaadf7d72", "tree": "471ac26edd4fbdfda5a3b091b9d583d579c882cb", "parents": [ "67a3e12b05e055c0415c556a315a3d3eb637e29e" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Jun 02 22:04:39 2010 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Jun 02 22:04:39 2010 -0400" }, "message": "ext4: Make sure the MOVE_EXT ioctl can\u0027t overwrite append-only files\n\nDan Roseberg has reported a problem with the MOVE_EXT ioctl.
