kmem_cache_alloc() return value check
kmem_cache_alloc() only return two possible value: NULL for error,
and non-NULL for valid pointer. IS_ERR() check for return value is
not right, I guessed?

system unresponsive after issuing a zpool attach
Today I attempted to upgrade to S10_U2 and migrate some mirrored UFS SVM
partitions to ZFS.
I used Live Upgrade to migrate from U1 to U2 and that went without a
hitch on my SunBlade 2000. And the initial conversion of one side of the
UFS mirrors to a ZFS pool and subsequent data migration went fine.
However, when I attempted to attach the second side mirrors as a mirror
of the ZFS pool, all

Anybody seeing this OOPS
Hello All,
I am running Linux 2.4.7-10, 2.4.18-4 and 2.4.19-pre9, I
see the following oops quite often (mainly on 2.4.19-pre9 with
kdb). All the kernels I use have the kdb patch installed.

[PATCH] btrfs: mask out gfp flasg in releasepage
btree_releasepage is a callback and can be passed unknown gfp flags and then

This may happen when btrfs is mounted from a loop device, which masks out
