From inspection, I can't find any code paths = that would result in the "struct stat" buffer being uninitialized. Plus, nfscl_cberrmap+0xb86 does not lie within any known function, according to k= gdb. Unless I can produce a build where KMSAN can correctly determine the locat= ion of the offending function, this will be impossible to fix. --=20 You are receiving this mail because: You are the assignee for the bug.=
