Lustre-patch breaks quota_v2.c

[Chris Jewell]

Hi,

I am trying to patch the kernel sources from linux-source-2.6.27-17.46_all.deb using the config from the corresponding linux-image package, since I noticed that patches for 2.6.27 vanilla were present in the lustre-patch package. After patching the (broken) kernel source (bug in arch/x86/kernel/entry_64.S), the patched build fails at quota_v2.c:

fs/quota_v2.c: In function ‘v2_read_file_info’:
fs/quota_v2.c:127:17: error: ‘qinfo’ undeclared (first use in this function)
fs/quota_v2.c:127:17: note: each undeclared identifier is reported only once for each function it appears in
fs/quota_v2.c: In function ‘v2r0_is_id’:
fs/quota_v2.c:206:43: error: ‘struct mem_dqinfo’ has no member named ‘dqi_priv’
fs/quota_v2.c: In function ‘v2r1_mem2diskdqb’:
fs/quota_v2.c:238:43: error: ‘struct mem_dqinfo’ has no member named ‘dqi_priv’
make[2]: *** [fs/quota_v2.o] Error 1

This error does *not* occur if I compile an unpatched version of the kernel sources. Is this bug appearing because I'm trying to patch 2.6.27 (I notice the lustre-patch package doc gives the latest kernel version as 2.6.22), or is it something more general I wonder?

Regards,

Chris
