Darrick J. Wong 4528b90527 xfs: allow sysadmins to specify a maximum atomic write limit at mount time ... Introduce a mount option to allow sysadmins to specify the maximum size of an atomic write. If the filesystem can work with the supplied value, that becomes the new guaranteed maximum. The value mustn't be too big for the existing filesystem geometry (max write size, max AG/rtgroup size). We dynamically recompute the tr_atomic_write transaction reservation based on the given block size, check that the current log size isn't less than the new minimum log size constraints, and set a new maximum. The actual software atomic write max is still computed based off of tr_atomic_ioend the same way it has for the past few commits. Note also that xfs_calc_atomic_write_log_geometry is non-static because mkfs will need that. Signed-off-by: Darrick J.
