pdj-fstest mkdir/rm error messages again

pdj-fstest mkdir/rm error messages again

[Thomas Mueller]

hi

for a while the pdj-fstest worked without error messages. 

now the pdj-fstest says again "successfull" but prints these:

/home/tmu//home/tmu/src/ceph-testsuite/tools/pjd-fstest-20080816/tests/chmod/02.t ..... ok
mkdir: cannot create directory `_xxxxveryveryveryverylongxxxxxxxxxxx': File name too long
rm: cannot remove `_xxveryveryveryverylongxxxxxx': File name too long
/home/tmu/src/ceph-testsuite/tools/pjd-fstest-20080816/tests/chmod/03.t ..... oksrc/ceph-testsuite/tools/pjd-fstest-20080816/tests/chmod/02.t ..... ok
mkdir: cannot create directory `_xxxxveryveryveryverylongxxxxxxxxxxx': File name too long
rm: cannot remove `_xxveryveryveryverylongxxxxxx': File name too long
/home/tmu/src/ceph-testsuite/tools/pjd-fstest-20080816/tests/chmod/03.t ..... ok


ceph.git revs (maybe this is kclient related and this means nothing):
rev ok: 
658d51dae14a724f167a02f18ebce19ca943f465 (2010-06-13 10:25:45 CEST)

rev bad again: 
658d51dae14a724f167a02f18ebce19ca943f465 (2010-06-14 16:32:03 CEST)

This is a kernel client thing that was fixed by 
558d3499bd059d4534b1f2b69dc1c562acc733fe (merged into 2.6.35-rc3).  Can 
you confirm that you saw this with something older than that?

Thanks-

this is on ceph-client-standalone/unstable-backport ref 
fe5b9c28ed9cfeb450233d7fedced4203f7a1d64 

compiled and loaded the module again. the messages are reproducable.

Oh, the ceph-client-standalone.git hadn't been resynced with 
ceph-client.git recently.  I just updated it, and it now includes the 
f_namelen fix.
