Revision 6af10a33c501b0b5878476501143c2cfbbfd63a2 authored by Yufen Yu on 20 August 2020, 13:22:05 UTC, committed by Song Liu on 28 August 2020, 05:41:03 UTC
Commit 3b5408b98e4d ("md/raid5: support config stripe_size by sysfs
entry") make stripe_size as a configurable value. It just requires
stripe_size as multiple of 4KB.
In fact, we should make sure stripe_size as power of two. Otherwise,
stripe_shift which is the result of ilog2 can not represent the real
stripe_size. Then, stripe_hash() and stripe_hash_locks_hash() may
get unexpected value.
