* jbd: correctly unescape journal data blocksDuane Griffin2008-03-19
| | | | | | | | | | | | | | | | | | Fix a long-standing typo (predating git) that will cause data corruption if a journal data block needs unescaping. At the moment the wrong buffer head's data is being unescaped. To test this case mount a filesystem with data=journal, start creating and deleting a bunch of files containing only JFS_MAGIC_NUMBER (0xc03b3998), then pull the plug on the device. Without this patch the files will contain zeros instead of the correct data after recovery.

* BKL-removal: remove incorrect comment refering to lock_kernel() from jbd/jbd2Andi Kleen2008-02-06
| | | | | | | | | | | None of the callers of this function does actually take the BKL as far as I can see. So remove the comment refering to the BKL.

* JBD: Fix JBD warnings when compiling with CONFIG_JBD_DEBUGJose R. Santos2007-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Note from Mingming's JBD2 fix: Noticed all warnings are occurs when the debug level is 0. Then found the "jbd2: Move jbd2-debug file to debugfs" patch http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0f49d5d019afa4e94253bfc92f0daca3badb990b changed the jbd2_journal_enable_debug from int type to u8, makes the jbd_debug comparision is always true when the debugging level is 0. Thus the compile warning occurs. Thought about changing the jbd2_journal_enable_debug data type back to int, but can't, because the jbd2-debug is moved to debug fs, where calling debugfs_create_u8() to create the debugfs entry needs the value to be u8 type. Even if we changed the data type back to int, the code is still buggy, kernel should not print jbd2 debug message if the jbd2_journal_enable_debug is set to 0. But this is not the case. The fix is change the level of debugging to 1. The same should fixed in ext3/JBD, but currently ext3 jbd-debug via /proc fs is broken, so we probably should fix it all together.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
