seq_file: properly cope with pread

2009-03-17T00:31:56+00:00

commit 8f19d472935c83d823fa4cf02bcc0a7b9952db30 upstream. Currently seq_read assumes that the offset passed to it is always the offset it passed to user space. In the case pread this assumption is broken and we do the wrong thing when presented with pread. To solve this I introduce an offset cache inside of struct seq_file so we know where our logical file position is. Then in seq_read if we try to read from another offset we reset our data structures and attempt to go to the offset user space wanted.

seq_file: add seq_cpumask_list(), seq_nodemask_list()

2008-10-20T15:52:39+00:00

seq_cpumask_list(), seq_nodemask_list() are very like seq_cpumask(), seq_nodemask(), but they print human readable string. Signed-off-by: Lai Jiangshan Cc: Alexey Dobriyan Cc: Paul Menage Cc: Paul Jackson Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

seq_file: add seq_cpumask(), seq_nodemask()

2008-08-12T23:07:30+00:00

Short enough reads from /proc/irq/*/smp_affinity return -EINVAL for no good reason. This became noticed with NR_CPUS=4096 patches, when length of printed representation of cpumask becase 1152, but cat(1) continued to read with 1024-byte chunks. bitmap_scnprintf() in good faith fills buffer, returns 1023, check returns -EINVAL. Fix it by switching to seq_file, so handler will just fill buffer and doesn't care about offsets, length, filling EOF and all this crap. For that add seq_bitmap(), and wrappers around it -- seq_cpumask() and seq_nodemask().

[patch 2/7] vfs: mountinfo: add seq_file_root()

2008-04-23T04:04:38+00:00

Add a new function: seq_file_root() This is similar to seq_path(), but calculates the path relative to the given root, instead of current->fs->root. If the path was unreachable from root, then modify the root parameter to reflect this. Signed-off-by: Miklos Szeredi Signed-off-by: Al Viro

[patch 1/7] vfs: mountinfo: add dentry_path()

2008-04-23T04:04:32+00:00

[mszeredi@suse.cz] split big patch into managable chunks Add the following functions: dentry_path() seq_dentry() These are similar to d_path() and seq_path(). But instead of calculating the path within a mount namespace, they calculate the path from the root of the filesystem to a given dentry, ignoring mounts completely.
