Here's a revised version of Bob's gfs2_log_header_v2 patches from January 4:
The first patch cleanus up get_log_header in a preliminary step. The second patch incorporates the following chages: * Fix a NULL pointer access when recovering a node's own journal (sdp->sd_qc_inode is NULL in gfs2_write_log_header in that case). * Move the call to gfs2_log_bmap out of gfs2_log_write. With that, lh_crc can be computed in gfs2_write_log_header and no separate gfs2_set_log_csum function is needed anymore. * Change lh_crc to only cover the rest of the block excluding the v1 log header: there is no point in crc-protecting the v1 header a second time. * Since lh_crc covers the rest of the block and not only a few header fields, it makes sense to use crc32c, which is much faster on architectures that implement it in hardware. The third patch is unchanged from Bob's last version.
