make set_blocksize() fail unless block device is opened exclusive (2024-05-02 17:39:44 -0400)
----------------------------------------------------------------
getting rid of bogus set_blocksize() uses, switching it
to struct file * and verifying that caller has device
opened exclusively.
----------------------------------------------------------------
Al Viro (9):
bcache_register(): don't bother with set_blocksize()
pktcdvd: sort set_blocksize() calls out
swapon(2)/swapoff(2): don't bother with block size
swapon(2): open swap with O_EXCL
zram: don't bother with reopening - just use O_EXCL for open
swsusp: don't bother with setting block size
btrfs_get_bdev_and_sb(): call set_blocksize() only for exclusive opens
set_blocksize(): switch to passing struct file *
make set_blocksize() fail unless block device is opened exclusive
