![]() Under certain circumstances, spin_is_locked() is hardwired to 0 - even when the
code would normally be in a locked section where it should return 1. This
means it cannot be used for an assertion that checks that a spinlock is locked.
Remove such usages from FS-Cache.
The following oops might otherwise be observed:
FS-Cache: Assertion failed
BUG: failure at fs/fscache/operation.c:270/fscache_start_operations()!
