parallel\npatch to mkfs.exofs that enables multi-device capabilities.\n\nAfter this patch, old exofs will refuse to mount a new formatted FS and\nnew exofs will refuse an old format. This is done by moving the magic\nfield offset inside the FSCB. A new FSCB *version* field was added. In\nthe future, exofs will refuse to mount unmatched FSCB version. To\nup-grade or down-grade an exofs one must use mkfs.exofs --upgrade option\nbefore mounting.\n\nIntroduced, a new object that contains a *device-table*. This object\ncontains the default *data-map* and a linear array of devices\ninformation, which identifies the devices used in the filesystem. This\nobject is only written to offline by mkfs.exofs. This is why it is kept\nseparate from the FSCB, since the later is written to while mounted.\n\nSame partition number, same object number is used on all devices only\nthe device varies.\n\n* define the new format, then load the device table on mount time make\n sure every thing is supported.\n\n* Change I/O engine to now support Mirror IO, .i.e write same data\n to multiple devices, read from a random device to spread the\n read-load from multiple clients (TODO: stripe read)\n\nImplementation notes:\n A few points introduced in previous patch should be mentioned here:\n\n* Special care was made so absolutlly all operation that have any chance\n of failing are done before any osd-request is executed. This is to\n minimize the need for a data consistency recovery, to only real IO\n errors.\n\n* Each IO state has a kref. It starts at 1, any osd-request executed\n will increment the kref, finally when all are executed the first ref\n is dropped. At IO-done, each request completion decrements the kref,\n the last one to return executes the internal _last_io() routine.\n _last_io() will call the registered io_state_done. On sync mode a\n caller does not supply a done method, indicating a synchronous\n request, the caller is put to sleep and a special io_state_done is\n registered that will awaken the caller. Though also in sync mode all\n operations are executed in parallel.\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\n" }, { "commit": "06886a5a3dc5a5abe0a4d257c26317bde7047be8", "tree": "858ac56e120c0473d764fc64a2660e6d79729c8c", "parents": [ "8ce9bdd1fbe962933736d7977e972972cd5d754c" ], "author": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Sun Nov 08 14:54:08 2009 +0200" }, "committer": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Thu Dec 10 09:59:22 2009 +0200" }, "message": "exofs: Move all operations to an io_engine\n\nIn anticipation for multi-device operations, we separate osd operations\ninto an abstract I/O API.

In current EXT4_IOC_MOVE_EXT, there are read access mode checks for\noriginal and donor files, but they allow the illegal write access to\ndonor file, since donor file is overwritten by original file data. To\nfix this problem, change access mode checks of original (r-\u003er/w) and\ndonor (r-\u003ew) files.\n\n2. Disallow the use of donor files that have a setuid or setgid bits.\n\n3. Call mnt_want_write() and mnt_drop_write() before and after\next4_move_extents() calling to get write access to a mount.\n\nSigned-off-by: Akira Fujita \u003ca-fujita@rs.jp.nec.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "b436b9bef84de6893e86346d8fbf7104bc520645", "tree": "50fb9ae167bcd622e9adf47646bcf3b4c7dd111d", "parents": [ "194074acacebc169ded90a4657193f5180015051" ], "author": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Tue Dec 08 23:51:10 2009 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Tue Dec 08 23:51:10 2009 -0500" }, "message": "ext4: Wait for proper transaction commit on fsync\n\nWe cannot rely on buffer dirty bits during fsync because pdflush can come\nbefore fsync is called and clear dirty bits without forcing a transaction\ncommit.

As the result it makes thread_group_cputime()\n to return pure sum of \"raw\" values.\n\n - Introduce a new function thread_group_times(*task, *utime, *stime)\n that converts \"raw\" values of thread_group_cputime() to \"adjusted\"\n values, in same calculation procedure as task_times().\n\n - Modify group\u0027s exit (\u003d wait_task_zombie()) to use this introduced\n thread_group_times().

fixed a race in the generic code, and as a\nside effect, now do_generic_file_read() can ask us to readpage() past\nthe i_size. This seems to be correctly handled by the block routines\n(e.g. block_read_full_page() fills the page with zeroes in case if\nsomebody is trying to read past the last inode\u0027s block).\n\nJFFS2 doesn\u0027t handle this; it assumes that it won\u0027t be asked to read\npages which don\u0027t exist -- and thus that there will be at least _one_\nvalid \u0027frag\u0027 on the page it\u0027s being asked to read. It will fill any\nholes with the following memset:\n\n memset(buf, 0, min(end, frag-\u003eofs + frag-\u003esize) - offset);\n\nWhen the \u0027closest smaller match\u0027 returned by jffs2_lookup_node_frag() is\nactually on a previous page and ends before \u0027offset\u0027, that results in:\n\n memset(buf, 0, \u003chuge unsigned negative\u003e);\n\nHopefully, in most cases the corruption is fatal, and quickly causing\nrandom oopses, like this:\n\n root@10.0.0.4:~/ltp-fs-20090531# ./testcases/kernel/fs/ftest/ftest01\n Unable to handle kernel paging request for data at
