I just ran into this issue with git today, where some operations locked up permanently (seemed to be an infinite readdir loop as described elsewhere in this thread). I applied this patch, and it solves the lockups, but there's a new problem: the directory list sometimes comes back _empty_! Here's the test script I used: #!/bin/sh -e mkdir gittest cd gittest git init for i in `seq 500` do printf 'Hello\nWorld!\n' > $i.txt done git add ./*.txt git commit -m 'Initial Commit' sed -i 1d ./*.txt git stash git stash pop echo 'Directory listing:' ls the 'ls' at the end prints nothing when the directory actually contains 500 files. If we insert an 'ls' just before the 'git stash pop', that one prints the full listing. Touching the directory afterwards makes the listings work again. The script works fine on 2.6.36. -- Nick Bowler, Elliptic Technologies (http://www.elliptictech.com/) -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
