reiserfs: avoid tail packing if an inode was ever mmapped

2007-02-03T01:38:47+00:00

This patch fixes a confusion reiserfs has for a long time. On release file operation reiserfs used to try to pack file data stored in last incomplete page of some files into metadata blocks. After packing the page got cleared with clear_page_dirty. It did not take into account that the page may be mmaped into other process's address space. Recent replacement for clear_page_dirty cancel_dirty_page found the confusion with sanity check that page has to be not mapped. The patch fixes the confusion by making reiserfs avoid tail packing if an inode was ever mmapped. reiserfs_mmap and reiserfs_file_release are serialized with mutex in reiserfs specific inode. reiserfs_mmap locks the mutex and sets a bit in reiserfs specific inode flags. reiserfs_file_release checks the bit having the mutex locked. If bit is set - tail packing is avoided. This eliminates a possibility that mmapped page gets cancel_page_dirty-ed. Signed-off-by: Vladimir Saveliev Signed-off-by: Adrian Bunk

Make 'repair' actually work for raid1.

2007-02-03T00:56:23+00:00

When 'repair' finds a block that is different one the various parts of the mirror. it is meant to write a chosen good version to the others. However it currently writes out the original data to each. The memcpy to make all the data the same is missing. Also correct a test so that 'repair' causes a repair, rather than anything other then 'repair'.

[SCSI] arcmsr: fix up sysfs values

2007-01-30T20:23:00+00:00

The sysfs files in arcmsr are non-standard in that they aren't simple filename value pairs, the values actually contain preceeding text which would have to be parsed. The idea of sysfs files is that the file name is the description and the contents is a simple value. Fix up arcmsr to conform to this standard.
