[OpenAFS-devel] Hangs during mv

[Harald Barth]

Hi everyone,

We have 1.3.82 with dcache patch on Linux 2.6.11.8+PDC and that gives
us processes that hang in a ranlib or mv (ranlib does a rename in
the end). My guess it that it is either

caused by DELTA linux-writepage-sync-20050308

or

maybe fixed by DELTA linux-vnode-aliases-20050529

or both ;-) Can you tell me which?
(I suppose Derrick has been near this code lately)

As usual many thanks for all the files,
Harald.
