Hi!

all files in the ./temp directory should be reloaded at startup.

access to the directory in the strace output:

      --

      [pid 21381] stat64("/mnt/reiser4/overtest/temp",  <unfinished ...>
      [pid 21379] write(0, "n", 1n <unfinished ...>
      [pid 21381] <... stat64 resumed> {st_mode=S_IFDIR|S_ISVTX|0755,

i cannot tell if this is correct (stat64...=0)


the whole strace is attached. (sent to nikita)

after the test, the filesystem was _corrupt again_ (wasnt before) - fscp
output attached (also sent to nikita)

      ...

p.s. i have harddrive writecache turned on - is this good/bad/should'nt
matter ? (again - no problems under reiser3)

hdparm /dev/hdb

/dev/hdb:
   multcount    = 16 (on)
   IO_support   =  1 (32-bit)
   unmaskirq    =  1 (on)
   using_dma    =  1 (on)
   readahead    = 256 (on)
   geometry     = 39770/16/63, sectors = 40088160, start = 0
   AdvancedPM=no WriteCache=enabled
