xfs: limit superblock corruption errors to actual corruption
Today, if
xfs_sb_read_verify
xfs_sb_verify
xfs_mount_validate_sb
detects superblock corruption, it'll be extremely noisy, dumping
2 stacks, 2 hexdumps, etc.
This is because we call XFS_CORRUPTION_ERROR in xfs_mount_validate_sb
as well as in xfs_sb_read_verify.
Also, *any* errors in xfs_mount_validate_sb which are not corruption
per se; things like too-big-blocksize, bad version, bad magic, v1 dirs,
rw-incompat etc - things which do not return EFSCORRUPTED - will
still do the whole XFS_CORRUPTION_ERROR spew when xfs_sb_read_verify
sees any error at all. And it suggests to the user that they
should run xfs_repair, even if the root cause of the mount failure
is a simple incompatibility.
I'll submit that the probably-not-corrupted errors don't warrant
this much noise, so this patch removes the warning for anything
other than EFSCORRUPTED returns, and replaces the lower-level
XFS_CORRUPTION_ERROR with an xfs_notice().
