xfs: remove inst_t

2015-06-21T23:44:02+00:00

We can simply use a void pointer to pass a long return addresses in the debugging helpers. Signed-off-by: Christoph Hellwig Reviewed-by: Brian Foster Signed-off-by: Dave Chinner

xfs: pass mp to XFS_WANT_CORRUPTED_RETURN

2015-02-23T11:39:13+00:00

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.

xfs: global error sign conversion

2014-06-25T04:58:08+00:00

Convert all the errors the core XFs code to negative error signs like the rest of the kernel and remove all the sign conversion we do in the interface layers. Errors for conversion (and comparison) found via searches like: $ git grep " E" fs/xfs $ git grep "return E" fs/xfs $ git grep " E[A-Z].*;$" fs/xfs Negation points found via searches like: $ git grep "= -[a-z,A-Z]" fs/xfs $ git grep "return -[a-z,A-D,F-Z]" fs/xfs $ git grep " -[a-z].*;" fs/xfs [ with some bits I missed from Brian Foster ] Signed-off-by: Dave Chinner Reviewed-by: Brian Foster Signed-off-by: Dave Chinner

xfs: Nuke XFS_ERROR macro

2014-06-22T05:04:54+00:00

XFS_ERROR was designed long ago to trap return values, but it's not runtime configurable, it's not consistently used, and we can do similar error trapping with ftrace scripts and triggers from userspace. Just nuke XFS_ERROR and associated bits. Signed-off-by: Eric Sandeen Reviewed-by: Dave Chinner Signed-off-by: Dave Chinner

xfs: add xfs_verifier_error()

2014-02-27T04:21:07+00:00

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. (Defined to EBADMSG, bad message) Signed-off-by: Eric Sandeen Reviewed-by: Dave Chinner Signed-off-by: Dave Chinner

xfs: kill support/debug.[ch]

2011-03-06T23:09:35+00:00

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. This allows fs/xfs/support/debug.[ch] to be completely removed from the codebase. Signed-off-by: Dave Chinner Reviewed-by: Alex Elder Reviewed-by: Christoph Hellwig

xfs: kill xfs_fs_mount_cmn_err() macro

2011-03-06T23:04:35+00:00

The xfs_fs_mount_cmn_err() hides a simple check as to whether the mount path should output an error or not. Remove the macro and open code the check. Signed-off-by: Dave Chinner Reviewed-by: Alex Elder Reviewed-by: Christoph Hellwig

xfs: kill xfs_fs_repair_cmn_err() macro

2011-03-06T23:03:35+00:00

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.

xfs: convert xfs_cmn_err to xfs_alert_tag

Continue the conversion of the old cmn_err interface be converting all the conditional panic tag errors to xfs_alert_tag() and then removing xfs_cmn_err(). Signed-off-by: Dave Chinner Reviewed-by: Alex Elder Reviewed-by: Christoph Hellwig
