cciss: fix problem that deleting multiple logical drives could cause a panic

2008-12-19T07:14:07+00:00

Fix problem that deleting multiple logical drives could cause a panic. It fixes a panic which can be easily reproduced in the following way: Just create several "arrays," each with multiple logical drives via hpacucli, then delete the first array, and it will blow up in deregister_disk(), in the call to get_host() when it tries to dig the hba pointer out of a NULL queue pointer. The problem has been present since my code to make rebuild_lun_table behave better went in. Signed-off-by: Stephen M. Cameron Signed-off-by: Jens Axboe

cciss: fix regression firmware not displayed in procfs

2008-11-06T23:41:18+00:00

This regression was introduced by commit 6ae5ce8e8d4de666f31286808d2285aa6a50fa40 ("cciss: remove redundant code"). This patch fixes a regression where the controller firmware version is not displayed in procfs. The previous patch would be called anytime something changed. This will get called only once for each controller. Signed-off-by: Mike Miller Cc: FUJITA Tomonori Cc: Jens Axboe Cc: [2.6.27.x] Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

cciss: fix sysfs broken symlink regression

2008-11-06T23:41:17+00:00

Regression introduced by commit 6ae5ce8e8d4de666f31286808d2285aa6a50fa40 ("cciss: remove redundant code"). This patch fixes a broken symlink in sysfs that was introduced by the above commit. We broke it in 2.6.27-rc on or about 20080804. Some installers are broken if this symlink does not exist and they may not detect the logical drives configured on the controller. It does not require being backported into 2.6.26.x or earlier kernels. Signed-off-by: Mike Miller Cc: Jens Axboe Cc: [2.6.27.x] Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] beginning of methods conversion

2008-10-21T11:47:32+00:00

To keep the size of changesets sane we split the switch by drivers; to keep the damn thing bisectable we do the following: 1) rename the affected methods, add ones with correct prototypes, make (few) callers handle both. That's this changeset. 2) for each driver convert to new methods. *ALL* drivers are converted in this series. 3) kill the old (renamed) methods. Note that it _is_ a flagday; all in-tree drivers are converted and by the end of this series no trace of old methods remain. The only reason why we do that this way is to keep the damn thing bisectable and allow per-driver debugging if anything goes wrong. New methods: open(bdev, mode) release(disk, mode) ioctl(bdev, mode, cmd, arg) /* Called without BKL */ compat_ioctl(bdev, mode, cmd, arg) locked_ioctl(bdev, mode, cmd, arg) /* Called with BKL, legacy */ Signed-off-by: Al Viro

drivers/block: Use DIV_ROUND_UP

2008-10-09T06:56:19+00:00

The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) / (d)) but is perhaps more readable. An extract of the semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @haskernel@ @@ #include @depends on haskernel@ expression n,d; @@ ( - (n + d - 1) / d + DIV_ROUND_UP(n,d) | - (n + (d - 1)) / d + DIV_ROUND_UP(n,d) ) @depends on haskernel@ expression n,d; @@ - DIV_ROUND_UP((n),d) + DIV_ROUND_UP(n,d) @depends on haskernel@ expression n,d; @@ - DIV_ROUND_UP(n,(d)) + DIV_ROUND_UP(n,d) // Signed-off-by: Julia Lawall Cc: Signed-off-by: Andrew Morton Signed-off-by: Jens Axboe

cciss: fix bug if scsi tape support is disabled
