(gdb) p/x mutex $2 = {__data = {__lock = 0x1, __count = 0x0, __owner = 0xedf, __nusers = 0x1, __kind = 0x0, __spins = 0x0, __elision = 0x0, __list = {__prev = 0x0, __next = 0x0}}, __size = {0x1, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0xdf, 0xe, 0x0, 0x0, 0x1, 0x0
}, __align = 0x1}
The same on Dirk's machine (glibc-2.19-19.1.x86_64):
(gdb) p/x mutex $1 = {__data = {__lock = 0x1, __count = 0x0, __owner = 0x0, __nusers = 0x0, __kind = 0x100, __spins = 0x0, __elision = 0x3, __list = {__prev = 0x0, __next = 0x0}}, __size = {0x1, 0x0
, 0x1, 0x0, 0x0, 0x0, 0x0, 0x3, 0x0 }, __align = 0x1}
How do I tell glibc to use lock elision? Dirk, perhaps you still have those workarounds to run Groupwise and they're getting on the way? -- You are receiving this mail because: You are on the CC list for the bug.
