Subject: f2fs: remove false-positive bug_on
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d8c4256c17dac3e9ec0c441b81292d5d2044c89f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

f2fs: remove false-positive bug_on

For example,

f2fs_create
 - new_node_page is failed
 - handle_failed_inode
  - skip to add it into orphan list, since ni.blk_addr == NULL_ADDR
   : set_inode_flag(inode, FI_FREE_NID)

f2fs_evict_inode
 - EIO due to fault injection
 - f2fs_bug_on() is triggered

So, we don't need to call f2fs_bug_on in this case.
