Instead, use the new 'mtd_can_have_bb()', or just rely on 'mtd_block_markbad()'
return code, which will be -EOPNOTSUPP if bad blocks are not supported.Signed-off-by: Artem Bityutskiy

This patch teaches 'mtd_sync()' to do nothing when the MTD driver does
not have the '->sync()' method, which allows us to remove all direct
'mtd->sync' accesses.Signed-off-by: Artem Bityutskiy
Signed-off-by: David Woodhouse -
This patch makes the 'mtd_writev()' function more usable and logical. We first
teach it to fall-back to the 'default_mtd_writev()' function if the MTD driver
does not define its own '->writev()' method. Then we make block2mtd and JFFS2
just 'mtd_writev()' instead of 'default_mtd_writev()' function. This means we
can now stop exporting 'default_mtd_writev()' and instead, export
'mtd_writev()'. This is much cleaner and more logical, as well as allows us to
get read of another direct 'mtd->writev' access in JFFS2.Signed-off-by: Artem Bityutskiy
Signed-off-by: David Woodhouse -
Remove direct usage of the "mtd->point" function pointer. Instead,
test the mtd_point() return code for '-EOPNOTSUPP'.Signed-off-by: Artem Bityutskiy

Instead, use 'default_mtd_writev()' function which MTD provides.

This patch is part of a patch-set which changes the MTD interface
from 'mtd->func()' form to 'mtd_func()' form. We need this because
we want to add common code to to all drivers in the mtd core level,
which is impossible with the current interface when MTD clients
call driver functions like 'read()' or 'write()' directly.At this point we just introduce a new inline wrapper function, but
later some of them are expected to gain more code. E.g., the input
parameters check should be moved to the wrappers rather than be
duplicated at many drivers.This particular patch introduced the 'mtd_erase()' interface. The
following patches add all the other interfaces one by one.Signed-off-by: Artem Bityutskiy

after 250df6ed274d767da844a5d9f05720b804240197
(fs: protect inode->i_state with inode->i_lock), insert_inode_locked()
no longer returns the inode with I_NEW set on failure. However,
the error handler still calls unlock_new_inode() on failure,
which does a WARN_ON if I_NEW is not set, so any failure spews
a lot of warnings.We can just drop the unlock_new_inode() if insert_inode_locked()
fails here.Signed-off-by: Eric Sandeen

Seeing that just about every destructor got that INIT_LIST_HEAD() copied into
it, there is no point whatsoever keeping this INIT_LIST_HEAD in inode_init_once();
the cost of taking it into inode_init_always() will be negligible for pipes
and sockets and negative for everything else. Not to mention the removal of
boilerplate code from ->destroy_inode() instances...Signed-off-by: Al Viro

..to allow forcing of either compression scheme. This will override
compiled-in defaults. jffs2_compress is reworked a bit, as the lzo/zlib
override shares lots of code w/ the PRIORITY mode.v2: update show_options accordingly.
Signed-off-by: Andres Salomon
Signed-off-by: Artem Bityutskiy -
Currently jffs2 has compile-time constants (and .config options)
controlling whether or not the various compression/decompression
drivers are built in and enabled. This is fine for embedded
systems, but it clashes with distribution kernels. Distro kernels
tend to turn on everything; this causes OpenFirmware to fall
over, as it understands ZLIB-compressed inodes. Booting a kernel
that has LZO compression enabled, writing to the boot partition,
and then rebooting causes OFW to fail to read the kernel from
the filesystem. This is because LZO compression has priority
when writing new data to jffs2, if LZO is enabled.This patch adds mount option parsing, and a single supported
option ("compr=none"). This adds the flexibility of being
able to specify which compressor overrides on a per-superblock
basis. For now, we can simply disable compression;
additional flexibility coming soon.v2: kill some printks, and implement show_options as suggested
by Artem Bityutskiy.Signed-off-by: Andres Salomon

These modes are not necessarily for OOB only. Particularly, MTD_OOB_RAW
affected operations on in-band page data as well. To clarify these
options and to emphasize that their effect is applied per-operation, we

This moves logic for checking the cached ACL values from low-level
filesystems into generic code. The end result is a streamlined ACL
check that doesn't need to load the inode->i_op->check_acl pointer at
all for the common cached case.The filesystems also don't need to check for a non-blocking RCU walk
case in their acl_check() functions, because that is all handled at a
VFS layer.Signed-off-by: Linus Torvalds
