ceph: do not modify fi->frag in need_reset_readdir()
Commit f3c4ebe65ea1 ("ceph: using hash value to compose dentry offset")
modified "if (fpos_frag(new_pos) != fi->frag)" to "if (fi->frag |=
fpos_frag(new_pos))" in need_reset_readdir(), thus replacing a
comparison operator with an assignment one.
This looks like a typo which is reported by clang when building the
kernel with some warning flags:
fs/ceph/dir.c:600:22: error: using the result of an assignment as a
condition without parentheses [-Werror,-Wparentheses]
} else if (fi->frag |= fpos_frag(new_pos)) {
~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~
fs/ceph/dir.c:600:22: note: place parentheses around the assignment
to silence this warning
} else if (fi->frag |= fpos_frag(new_pos)) {
^
( )
fs/ceph/dir.c:600:22: note: use '!=' to turn this compound
assignment into an inequality comparison
} else if (fi->frag |= fpos_frag(new_pos)) {
^~
!=
