[for-linus][PATCH 2/2] eventfs: Fix bitwise fields for "is_events"

From: Steven Rostedt
Date: Tue Jan 02 2024 - 20:51:42 EST


From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx>

A flag was needed to denote which eventfs_inode was the "events"
directory, so a bit was taken from the "nr_entries" field, as there's not
that many entries, and 2^30 is plenty. But the bit number for nr_entries
was not updated to reflect the bit taken from it, which would add an
unnecessary integer to the structure.
