[fuse-devel] poll

[John P. H. <jph...@gm...>]

strace shows a loop including these lines in the file system server:

write(2, "unique: 115, opcode: POLL (40), "..., 54) = 54
write(2, "poll[3] ph: 0x1745140\n", 22) = 22
write(2, "hiofuse.c:234  poll /3390 fd 3. "..., 57) = 57
write(2, "NOTIFY: code=1 count=2 length=24"..., 33) = 33
writev(3, [{"\30\0\0\0\1\0\0\0\0\0\0\0\0\0\0\0", 16}, 
{"\24\0\0\0\0\0\0\0", 8}], 2) = 24
write(2, "hiofuse.c:239  notify 0\n", 24) = 24
write(2, "   poll[3] revents: 0x1\n", 24) = 24
write(2, "   unique: 115, success, outsize"..., 37) = 37
writev(3, [{"\30\0\0\0\0\0\0\0s\0\0\0\0\0\0\0", 16}, 
{"\1\0\0\0\0\0\0\0", 8}], 2) = 24
read(3, 
"@\0\0\0(\0\0\0t\0\0\0\0\0\0\0\2\0\0\0\0\0\0\0\365\1\0\0\364\1\0\0"..., 
135168) = 64
write(2, "unique: 116, opcode: POLL (40), "..., 54) = 54
write(2, "poll[3] ph: 0x1745140\n", 22) = 22
write(2, "hiofuse.c:234  poll /3390 fd 3. "..., 57) = 57
write(2, "NOTIFY: code=1 count=2 length=24"..., 33) = 33
writev(3, [{"\30\0\0\0\1\0\0\0\0\0\0\0\0\0\0\0", 16}, 
{"\24\0\0\0\0\0\0\0", 8}], 2) = 24
write(2, "hiofuse.c:239  notify 0\n", 24) = 24
write(2, "   poll[3] revents: 0x1\n", 24) = 24
write(2, "   unique: 116, success, outsize"..., 37) = 37
writev(3, [{"\30\0\0\0\0\0\0\0t\0\0\0\0\0\0\0", 16}, 
{"\1\0\0\0\0\0\0\0", 8}], 2) = 24
read(3, 
"@\0\0\0(\0\0\0u\0\0\0\0\0\0\0\2\0\0\0\0\0\0\0\365\1\0\0\364\1\0\0"..., 
135168) = 64

So the problem would appear to be in the kernel module.
