hi
i have notice that bread on the new kernel returns the "on disk" block
and not the cached block.
i.e. if i overwrite a file block, calling bread will return the OLD data
from disk,
and not the new data which is in the cache now.
i guess that the write is performs to the cache, but bread
doesn't know about it, and it reads the block from the disk.
( if i call sync() before bread, i get the new data )
i have tried the same code with kernel 2.2.14 and it works fine( i.e. i
get the recent data from the cache )
but kernel 2.3.99-pre8 changes this behavior.
is this a bug of a feature ?
please CC me for any answer
THX
