Subject: [PATCH 5.10 107/129] zonefs: Clear inode information flags on inode creation

From: Damien Le Moal <damien.lemoal@...nsource.wdc.com>

commit 694852ead287a3433126e7ebda397b242dc99624 upstream.

Ensure that the i_flags field of struct zonefs_inode_info is cleared to
0 when initializing a zone file inode, avoiding seeing the flag
ZONEFS_ZONE_OPEN being incorrectly set.

Fixes: b5c00e975779 ("zonefs: open/close zone on file open/close")
