[PATCH 5.15 203/374] f2fs: fix to check compress file in f2fs_move_file_range()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chao Yu <chao@xxxxxxxxxx>

[ Upstream commit fb9b65340c818875ea86464faf3c744bdce0055c ]

f2fs_move_file_range() doesn't support migrating compressed cluster
data, let's add the missing check condition and return -EOPNOTSUPP
for the case until we support it.

Fixes: 4c8ff7095bef ("f2fs: support data compression")
