Subject: scripts/tags.sh: Invoke 'realpath' via 'xargs'
From: Cristian Ciocaltea <cristian.ciocaltea@xxxxxxxxxxxxx>
commit 7394d2ebb651a9f62e08c6ab864aac015d27c64d upstream.
When COMPILED_SOURCE is set, running
make ARCH=x86_64 COMPILED_SOURCE=1 cscope tags
could throw the following errors:
scripts/tags.sh: line 98: /usr/bin/realpath: Argument list too long
cscope: no source files found
scripts/tags.sh: line 98: /usr/bin/realpath: Argument list too long
ctags: No files specified. Try "ctags --help".
This is most likely to happen when the kernel is configured to build a
large number of modules, which has the consequence of passing too many
arguments when calling 'realpath' in 'all_compiled_sources()'.
Let's improve this by invoking 'realpath' through 'xargs', which takes
care of properly limiting the argument list.
