Description:
This allows the user to examine and adjust the criteria by which
mtd returns -EUCLEAN from mtd_read(). If the maximum number of
bit errors that were corrected on any single region comprising
an ecc step (as reported by the driver) equals or exceeds this
value, -EUCLEAN is returned. Otherwise, absent an error, 0 is
returned. Higher layers (e.g., UBI) use this return code as an
indication that an erase block may be degrading and should be
scrutinized as a candidate for being marked as bad.
mtd returns -EUCLEAN from mtd_read() and mtd_read_oob(). If the

The initial value may be specified by the flash device driver.
If not, then the default value is ecc_strength.

block degradation, but high enough to avoid the consequences of
a persistent return value of -EUCLEAN on devices where sticky
bitflips occur. Note that if bitflip_threshold exceeds
ecc_strength, -EUCLEAN is never returned by mtd_read().
ecc_strength, -EUCLEAN is never returned by the read operations.
Conversely, if bitflip_threshold is zero, -EUCLEAN is always
returned, absent a hard error.
