[lustre-devel] [PATCH 5/8] staging/lustre/osc: extern declare osc_caches in a header

[Oleg Drokin]

This avoids frowned upon extern in the C file, and also
shuts down a sparse warning of
drivers/staging/lustre/lustre/osc/osc_dev.c:55:22: warning: symbol 'osc_caches' was not declared. Should it be static?
