f46d3e8522 modalias.prov: rename "class" and "tag" variables to "prev" and "next"
The old names are misleading.

5683c50270 modalias.prov: use standard "match any char not in set" glob pattern, and sed -E option
[^set] is not correct in glob (it's regexp construct). [!set] is.

sed: -n is not necessary. -e too. manpage recommends using -E instead of -r.

35e1f2fc73 modalias.prov: speed up, explain and make more correct combining code
The time to run on tests/* data decreased from 34.517s to 30.201s.

Do not allow combining of any glob meta characters, either in first
or second line.

The code is still buggy, it may attempt to combine
    modalias(abc[def]123)
    modalias(abc[dXf]123)
into
    modalias(abc[d[eX]f]123)
(presumably there won't be any such cases in real modules, but still).

Eliminate "| head -n1" - do it with bash string ops.

7cd7d838cf modalias.prov: group modalias lines by length
On my machine, out of 2604 modules, this reduces number of
"provides" items by ~800 (to 12689 items).

c2b1f3e458 modalias.prov: avoid a subshell (fork) in position check
This creates a subshell: ... && ( [ -z "$pos" ] || [ $n = $pos ] )

For example, processing ath9k.ko needed ~80 forks here.
Rather expensive.

This should do the same: ... && [ -z "$pos" -o "$n" = "$pos" ]

While at it, explain algorithm in comments.

653ec7d086 modalias.prov: use "local" builtin rather than "declare"
While (in this case) their effect is the same,
many more people know that "local" makes variables function-local,
than that "declare" in bash does the same. I didn't know.

underscores.

52ba5a74f2 modalias.prov: change interpreter to /bin/bash -efu
* modalias.prov: Chnge interpreter from "/bin/sh" to "/bin/bash" because
it uses bashisms;  add "-efu" flags to keep things in check; initialise
is_kernel_package variable; check for presence of /sbin/modinfo, sed,
and sort.
(combine_modaliases): Initialise the "variants" and "pos" variables.
