Subject: libxfs: don't use enum for buffer flags
X-Git-Tag: v5.2.0~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3a3f5b14a49182d345a061eaff198aa22e7444c7;p=thirdparty%2Fxfsprogs-dev.git

libxfs: don't use enum for buffer flags

This roughly mirrors

  807cbbdb xfs: do not use emums for flags used in tracing

and lets us use the xfs_buf_flags_t type in function calls as is
done in the kernel.
