[PATCH 09/25] libxfs: make libxfs_readbufr stash the error value in b_error

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

 



From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>

Make libxfs_readbufr stash the error value in b_error, which will make
the behavior consistent between regular and multi-mapping buffers.
