Today, if we hit an XFS_WANT_CORRUPTED_RETURN we don't print any information about which filesystem hit it. Passing in the mp allows us to print the filesystem (device) name, which is a pretty critical piece of information. Tested by running fsfuzzer 'til I hit some.

We want to distinguish between corruption, CRC errors, etc. In addition, the full stack trace on verifier errors seems less than helpful; it looks more like an oops than corruption. Create a new function to specifically alert the user to verifier errors, which can differentiate between EFSCORRUPTED and CRC mismatches. It doesn't dump stack unless the xfs error level is turned up high. Define a new error message (EFSBADCRC) to clearly identify CRC errors.

The remaining functionality in debug.[ch] is effectively just assert handling, conditional debug definitions and hex dumping. The hex dumping and assert function can be moved into the new printk module, while the rest can be moved into top-level header files.

In certain cases of inode corruption, the xfs_fs_repair_cmn_err() macro is used to output an extra message in the corruption report. That extra message is "unmount and run xfs_repair", which really applies to any corruption report. Each case that this macro is called (except one) a following call to xfs_corruption_error() is made to optionally dump more information about the error. Hence, move the output of "run xfs_repair" to xfs_corruption_error() so that it is output on all corruption reports. Also, convert the callers of the repair macro that don't call xfs_corruption_error() to call it, hence provide consiѕtent error reporting for all cases where xfs_fs_repair_cmn_err() used to be called.

We currently have a global error message buffer in cmn_err that is protected by a spin lock that disables interrupts. Recently there have been reports of NMI timeouts occurring when the console is being flooded by SCSI error reports due to cmn_err() getting stuck trying to print to the console while holding this lock (i.e. with interrupts disabled). The NMI watchdog is seeing this CPU as non-responding and so is triggering a panic. While the trigger for the reported case is SCSI errors, pretty much anything that spams the kernel log could cause this to occur. Realistically the only reason that we have the intemediate message buffer is to prepend the correct kernel log level prefix to the log message. The only reason we have the lock is to protect the global message buffer and the only reason the message buffer is global is to keep it off the stack. Hence if we can avoid needing a global message buffer we avoid needing the lock, and we can do this with a small amount of cleanup and some preprocessor tricks: 1. clean up xfs_cmn_err() panic mask functionality to avoid needing debug code in xfs_cmn_err() 2. remove the couple of "!" message prefixes that still exist that the existing cmn_err() code steps over. 3. redefine CE_* levels directly to KERN_* 4. redefine cmn_err() and friends to use printk() directly via variable argument length macros. By doing this, we can completely remove the cmn_err() code and the lock that is causing the problems, and rely solely on printk() serialisation to ensure that we don't get garbled messages. A series of followup patches is really needed to clean up all the cmn_err() calls and related messages properly, but that results in a series that is not easily back portable to enterprise kernels. Hence this initial fix is only to address the direct problem in the lowest impact way possible.

Recent tests writing lots of small files showed the flusher thread being CPU bound and taking a long time to do allocations on a debug kernel. perf showed this as the prime reason: samples pcnt function DSO _______ _____ ___________________________ _________________ 224648.00 36.8% xfs_error_test [kernel.kallsyms] 86045.00 14.1% xfs_btree_check_sblock [kernel.kallsyms] 39778.00 6.5% prandom32 [kernel.kallsyms] 37436.00 6.1% xfs_btree_increment [kernel.kallsyms] 29278.00 4.8% xfs_btree_get_rec [kernel.kallsyms] 27717.00 4.5% random32 [kernel.kallsyms] Walking btree blocks during allocation checking them requires each block (a cache hit, so no I/O) call xfs_error_test(), which then does a random32() call as the first operation. IOWs, ~50% of the CPU is being consumed just testing whether we need to inject an error, even though error injection is not active. Kill this overhead when error injection is not active by adding a global counter of active error traps and only calling into xfs_error_test when fault injection is active.

xfs_fs_vcmn_err can be called under a spinlock, but does a sleeping memory allocation to create buffer for it's internal sprintf. Fortunately it's the only caller of icmn_err, so we can merge the two and have one single static buffer and spinlock protecting it. While we're at it make sure we proper __attribute__ format annotations so that the compiler can detect mismatched format strings.

Currently the xfs module init/exit code is a mess. It's farmed out over a lot of function with very little error checking. This patch makes sure we propagate all initialization failures properly and clean up after them. Various runtime initializations are replaced with compile-time initializations where possible to make this easier. The exit path is similarly consolidated. There's now split out function to create/destroy the kmem zones and alloc/free the trace buffers. I've also changed the ktrace allocations to KM_MAYFAIL and handled errors resulting from that. And yes, we really should replace the XFS_*_TRACE ifdefs with a single XFS_TRACE..

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!
