  "message": "[PATCH] sparc32 rwlock fix\n\nread_trylock() is broken on sparc32 (doesn\u0027t build and didn\u0027t work\nright, actually).  Proposed fix:\n\n - make \"writer holds lock\" distinguishable from \"reader tries to grab\n   lock\"\n\n - have __raw_read_trylock() try to acquire the mutex (in LSB of lock),\n   terminating spin if we see that there\u0027s writer holding it.  Then do\n   the rest as we do in read_lock().\n\nThanks to Ingo for discussion...\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
