| |
In an attempt to simplify some includes in <include/dcache.h>, it appeared, when compiling fs/ecryptfs/dentry.c, that <linux/bit_spinlock.h> was relying on other includes to get the definition of cpu_relax(). (see [1])
It broke on arc.
Include <asm/processor.h> in <linux/bit_spinlock.h> to fix the issue. This will help remove some un-needed includes from <include/dcache.h>.
