[PATCH] xfs/073: avoid large recurise diff

[Date Prev] [Date Next] [Thread Prev] [Thread Next] [Date Index] [Thread Index]



xfs/073 has been failing for me for a while on most of my test setups
with:

diff: memory exhausted

from the large recursive diff it does.  Replace that with a pipe using
md5sum to reduce the memory usage.

Based on a snipplet from Darrick Wong.
