2007-10-17jbd2: JBD_XXX to JBD2_XXX naming cleanupMingming Cao1-1/+1

2007-07-19fix ext4/JBD2 build warningsMingming Cao1-3/+3
Looking at the current linus-git tree jbd_debug() define in include/linux/jbd2.h extern u8 journal_enable_debug; #define jbd_debug(n, f, a...) \ do { \ if ((n) <= journal_enable_debug) { \ printk (KERN_DEBUG "(%s, %d): %s: ", \ __FILE__, __LINE__, __FUNCTION__); \ printk (f, ## a); \ } \ } while (0) > fs/ext4/inode.c: In function ‘ext4_write_inode’: > fs/ext4/inode.c:2906: warning: comparison is always true due to limited > range of data type > > fs/jbd2/recovery.c: In function ‘jbd2_journal_recover’: > fs/jbd2/recovery.c:254: warning: comparison is always true due to > limited range of data type > fs/jbd2/recovery.c:257: warning: comparison is always true due to > limited range of data type > > fs/jbd2/recovery.c: In function ‘jbd2_journal_skip_recovery’: > fs/jbd2/recovery.c:301: warning: comparison is always true due to > limited range of data type > 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.

2007-07-18jbd2: Fix CONFIG_JBD_DEBUG ifdef to be CONFIG_JBD2_DEBUGJose R. Santos1-1/+1
When the JBD code was forked to create the new JBD2 code base, the references to CONFIG_JBD_DEBUG where never changed to CONFIG_JBD2_DEBUG. This patch fixes that. Signed-off-by: Jose R. Santos <jrs@us.ibm.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2006-10-11[PATCH] 64-bit jbd2 coreZach Brown1-13/+30
Here is the patch to JBD to handle 64 bit block numbers, originally from Zach Brown. This patch is useful only after adding support for 64-bit block numbers in the filesystem.
