[PATCH] Btrfs: improve the BIO_RW_DISCARD conditional compile func definition
The conditional compile func definition shall better not be defined this way:
static int btrfs_issue_discard()
{
#ifdef BIO_RW_DISCARD
...
#else
return 0;
#endif
}
instead, can be better done this way:
#ifndef BIO_RW_DISCARD
static int btrfs_issue_discard()
{
return 0;
}
#endif
#ifdef BIO_RW_DISCARD
static int btrfs_issue_discard()
{
...
}
#endif
