From 04e99455ea5bb17ea7c2e7bb0970168efb736242 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 25 Jan 2011 09:06:19 +0000 Subject: [PATCH 01/23] xfs: only lock the rt bitmap inode once per allocation Currently both xfs_rtpick_extent and xfs_rtallocate_extent call xfs_trans_iget to grab and lock the rt bitmap inode, which results in a deadlock since the removal of the lock recursion counters in commit "xfs: simplify inode to transaction joining" Fix this by acquiring and locking the inode in xfs_bmap_rtalloc before calling into xfs_rtpick_extent and xfs_rtallocate_extent.

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.

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.
