2.4.7-xfs kernel BUG at dcache.c:345

[Lennert Buytenhek <buytenh@gnu.org>]

(please CC, not on the list)


Hi,

Looks like dentries with ->d_count != 0 are escaping to the dentry_unused
list.. (no idea whether this is xfs-specific, but all filesystems on this
box are xfs so this would be the first place to seek help).

Am willing to try patches.


cheers,
Lennert
