I don't understand the name change.
Pick a name. I don't much care what it is really.
This one takes a super_block * and emits a logging message so I chose jfs_sb_err to try to describe the sb * bit.
I like the _err suffix is a bit better than the _error suffix as it's a bit more name consistent with other kernel logging mechanisms like dev_err, pr_err, etc, but if you want to remain consistent with other fs/,,, fine by me.
I think the other fs _error names are sub-optimal.
These functions are a bit overloaded too when CONFIG_PRINTK is not enabled. The format and args still exist in code and I believe can not be optimized away by the compiler
I think using macro or an in-place expansion to separate the 2 parts of the reporting and then the handling of of the error would be better as it would allow smaller embedded use.

I submitted a patch a few years ago to do that too. Dunno what happened to it,

It also reduces stack needs a bit by removing that 256 byte temp buffer.
