[PATCH v2 01/10] staging: erofs: fix `trace_erofs_readpage' position

[Gao Xiang]

From: Gao Xiang <gaoxiang25 at huawei.com>

`trace_erofs_readpage' was designed for .readpage() interface hook
in order to trace the detailed synchronized read rather than
the internal implementation `z_erofs_do_read_page' which both
.readpage() and .readpages() use.

It seems the tracepoint was placed to a wrong place by mistake and
it should be moved to the right place.

Fixes: 284db12cfda3 ("staging: erofs: add trace points for reading zipped data")
