[PATCH 07/11] xfs_scrub: record disk LBA size

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

 



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

Remember the size (in bytes) of a logical block on the disk.  We'll use
this in subsequent patches to improve the ability of media scans to
report on which files are corrupt.
